Quadratrac to Dana 300 conversion

I'm a converting a 1976 CJ7 (quadratrac) with AMC 20 rearend to a Dana 300 with 44 rearend. I have everything except the shifter I have looked at the double stick shifter, but I don't really think that I want this. I have some concerns about mounting the shifter through the floor of the jeep, because I have a t4 auto trans. I don't have a hole already there, has anyone done this before that can give me some advise. I know that I can order the shifter but I didn't see the metal retainer that goes over the boot in my catalog,will this come with the boot if I order it?

Thanks

Davis,
The tranny is the TH400 (turbo 400) auto (texas pan) the t-4 you mentioned is a standard 4 speed.
There is an impression on the floor of the tunnel a large square or rectangle. this is cut out completely on standard jeeps and is replaced with a steel pan that is screwed down to the tunnel it has the holes cut for the two shifters.
you can find one from another jeep but will need to fill in the tranny shifter hole, or make your own pan from scratch.
or you could just cut a slot in the floor for the shifter and open it up as much as you need to be able to engage all ranges.
The shift boot comes with everything but the screws, the metal retainer is molded into the rubber on the replacement boots.

hey, id like to hear what happens with this swap. i dunno why but i was under the impression that with a 258 and th400 tranny that anything besides a quad transfer case would be too far back, unless you wanted the transfer case shifter between your seats. maybe im thinking of something else, either way let me know how this turns out, i might do the same thing.

Quadratrac to Dana 300 conversion

I started out with a AMC 304, so far I have installed a chevy 327, I did have to change the torque coverter on the 400 and also the tail shaft, I ordered a adapter from Advanced Adapters to adapt the 300TC with the th400 tran. the tail shaft came with it. I found a 44 under a 75 CJ5 in a salvage yard and had it rebuilt. I haven't put everything back together yet but I've been told that it will work. I also have bought a new radiator and edelbrock performer intake and headers. I just rebuilt the power steering box I've got a fortune in this now and can't afford to stop. Hopefully it will be nice when I'm finished.

Thanks for the comments.......

ps. I'm very interested in hearing anything about any simular conversions so Ya'll don't hold out!!

Just found out that I have to move the rear spring perches on the Dana44. I haven't done much yet, I'll keep everyone updated. I guess if the shifter has to be between the seats then thats were I'll have to put it. Has anyone ever done this????????

Isn't the rear portion of the 76's frame wider than the earlier CJ frame that the D44 came from? You might run into problems of the rear tires rubbing the frame. Suppose you could go with some deep rims or even wheel spacers. Something to check out... good luck

All '72-81 CJ's have the same width rear axle whether it's the Dana 44 or AMC 20. Yes the frame got wider in '76 and some people have trouble with rubbing if they have too much backspacing on their wheels. With the right wheels or lift it's not a problem though.

sdavis you need to find someone with a '80-86 CJ and look at where their shifter is. Yours will be in the same plane from side to side, but not necessarily front to back since your T400 is longer than any CJ manual tranny or auto used in those years.

there is a blank cover plate on ebay right now that would be perfect for this.

um, so a pre-76 axle wont be a direct bolt-in replacement to a 76-81 CJ? the spring perches will be closer together?

Yep, the pre-76 frame rails are 27.5" apart on center front front to rear. The '76-86 frame rails get farther apart starting right behind the firewall.

been there..

Here you go, don't get nervous but take your cover off and put the 300 in N or 4L which is forward. I heated the stick with a blue tip wrench and bent it so it was about 2.5 inches from the dash, now when you shift into 4H it will be just touching the back of the hole in you tunnel. Have I lost you? It's going to take a few bends and about a half hour to get it just right but it'll work and with min' cutting on the cover. It's got the curve of a Hurst shifter and it works, after bending dunk it in oil to harden it and your there. You've got a nice setup, should do real good.GL

Quadratrac to Dana 300 conversion

Hello everyone,
I work in Angola,Africa on a drilling rig 28days on 28 days off. I'm just arriving at work for a 28 day stay. While I was home I had my spring perches moved, no problem if you have a torch and a welder. I had a wedding anniversary plus Thanksgiving so I didn't get much else done. ya'll know how it is....
I don't have a digital camera yet I may get one after new years and I'll try to get some pictures. I'm looking forward to getting things rolling when I get home this time. I'll keep ya'll posted.
Ya'll have a Merry Christmas and A HAPPY NEW YEAR!!
