Metal or Fiberglass Tub replacement for 79 cj7 ?

My wife purchased me a 79 CJ7 and I have searched the threads with no luck so... I need some opinions one way or the other on my tub problem. I dont know much about fabrication and twice as less about welding. My tub has the floor rusted out except for the tranny hump from firewall to the riser to the rear seat. The firewall on driver side is 30% gone as well. All the side panels and the rest of the jeep body are in great shape and my frame, by the grace of God was in great shape. My delima is Im a fireman/medic with ten kids and this was sold to my wife as a "drivable project" and its not. So being the tightwad I am Im trying to decide if I spend the estimated $1000 to $1200 to have the floors redone or do I purchase a new fiberglass for $1500?? I need pros and cons please or ideas of another direction maybe?? Id post pics from my pc but have not figured that out yet...lol

Id stay with good ol' dentable steel. fiberglass just cracks. Maybe this is a oppertunity to learn to Fab and weld? I learned when i was 12. Once you get the hang of it, it is pretty easy.

Once you learn how to weld and fabricate a bit everything mechanical in nature just seems so much easier.

I would love to learn how to do welding and fabrication but I have neither an outlet to learn nor the time really. I barely have time to work on the jeep itself. I like the idea of sticking with the metal though. Its just killing me how expensive it is to have it done.

Just go with Glass. Once it's on and everything is okay, it is great to have a Jeep that looks great, all the time, year after year, forever pretty much.

I have an '86 glass CJ7 now, but I used to have a '75 CJ5 glass Jeep. Many people on the road would ask me how I like my brand new Jeep. And a lot of them freaked when I told them it was a '75.

first i wouldnt buy a new one. i would do exactly what i did again and that is buy a cj/yj tub off craigslist. i for example got an 88 yj tub. it is galvenized. had no rust and no dents. and was only $300. using a yj tub takes some minor modification but their is TONS of info on this forum and others on it. its very easy to do and if you plan on doing any wheeling it doesnt crack like glass. if its a looker and maybe some easy non wooded trails glass is better since it doesnt rust. its up to you but if you get a good deal on either, they both work fine

If I did it again I'd probably go steel and spray it with zinc. Well actually I didn't have a choice, PO did all the tub work.

Maybe it's just because it's AJ's, but I have had so many problems with things not fitting right. Missing body mounts, modified steering to dash brace, lengthened brake booster shaft, custom aluminum tailgate seal/latch, body just ain't square, both doors rub (tried putting driver door on other day and now I can't get it to fit), steel reinforcement not all where it should be & some where it shouldn't, steel reinforcement rusted out on hood hinges, hood fits crooked, windshield slightly crooked, dash trimmed on edges. Think I'm missing a few things.

I have to admit, knowing that you will never have to deal with a rusting body offsets most downfalls. Don't know if this is universal to paint and gel coat, but I have one hell of a time getting smashed bugs off the front of the fenders even with cutting creme. lol

yes. basically the only major difference is some of the mounts are a little off. easiest way to fix that is to cut and reweld the perches on the frame. search the forum, you will find many threads on it.

FIRESTOMPER I'm in the same boat, 79 CJ7 with lots of rust. LOTS of rust! I have pretty much been sold on the fiberglass but finding one has been just as daunting a task as steel. A total tub replacement is what I'm looking at and like you I'm on a budget. No RUST is why I'm looking forward to fiberglass seems to be a little easier to work with w/out welding skills. I too am a fireman and you may get some help from the guys at the station with the welding. It has paid off for me one of our guys is a whiz at electronics and another help with some issues I was having with the motor. Good Luck keep posting updates.

Once you learn to fab and weld your attractiveness to women as a self-reliant man goes up by a factor of 10.

Honestly, 'glass will flex more than you think before the cracking is apparent. And if it does crack, repair is easier than welding, just sand it down, repair the glass, and sand it smooth to shape. Paint is the only issue then, but it would be the same if you were cutting/welding... Granted, you will have to adapt things a bit for the 'glass, like I had to modify the track part for the Bestop Supertop when I put it on to match the curve as it was a little sharper than the track was, but then again I'd only recommend the Replace-a-Top from them anyways....

I have a glass 83 CJ7 and man do I have to adjust everything I put on it.
The aftermarket tube fenders don't line up so I had to move the mounting holes. The full hard doors don't sit flush all around. Everything you bolt on has to have a washer or so other kind of support behind it or the screws will rip out or crack the fiberglass. Everything electric needs a ground since the tub can't be used as a ground.

A steel tub you'll be fighting rust all the time unless you strip it clean and treat it. But if something doesn't line up you can tweak it a little without fear of the tub cracking.

If I had to do it again I might go for an aluminum tub or spend the cash and buy a steel and have it galvanized.

I found out about Jeeps late in life, so now I have to play catch up and get as many as I can. Man, life is great

You're a man with a large family so I'd wager your budget for both time and money is extremely tight.

The YJ tub would be the way to go if you can find one with minor/no rust issues. They are cheaper and easier to adapt than a new FG tub (there is no welding required for the body mounts as was previously eluded to). So you'd be dollars ahead as well as spend alot less time getting it back on the road.

FG may have some advantages but in your scenario I'd vote YJ tub all the way.

'84 CJ-7: Yota axles (spartan locked front, e-locked rear) 4" BDS, 1" Daystar & 3/8" shackle lifts, 35" X-Terrains on steelies, YJ Tub & family roll bar, heater blower upgrade, 4.2L w/MC2100 & Team Rush, Warn 8274. Rebuilt 4.2/4.0 hybrid, AX15 and twin sticks/clocking ring waiting to go in.

The advertised position for a topless, dirty jeep girl has been filled......by my wife. Thanks to all that applied.
<------------and yes, that is her.
:-D
