What does the term "intermediate" refer to with CJ5s

Ive recently acquired a 1974 CJ5, everyone refers to it as the intermediate CJ why is that?

The '72-75 CJs are a slightly different design from the earlier Willys version and the later '76-86 version.

72-75, they lengthened the front fenders/hood/frame to accommodate the strait 6 engine, but kept the tub/dash/windshield frame the same as the earlier models. For the 76 models they redesigned the dash and windshield frame. Kind of a transformation oddball set of years, some parts match from the 71 and earlier and some from the 76 and later when doing work on it.

I believe the dash design changed around '73. I also think '72 was the first year for the full-floater Dana 30 front axle.

It's an internet term, birthed by unknowns.

So would the dash just be flat steel, or would it have a dash pad? I've googled cj5 dash and seen both versions.

Open knuckle Dana 30, not full float. All front axles are full float.

There was a padded dash options, but it was different design from the 76+ as they changed the windshield hold downs.

Heater controls went from under the dash to in the dash panel in '76 and the steering column location also changed in the same manner along with being a different column. The 72-75 dash is the 99% the same as the '71 and older, other than bolt hole spacing on the sides where they bolt to the tub.

Not to hijack this thread (totally hijacking this thread), I'm looking at a '74 right now. Other than the dash, heater controls and box, are there any critical parts that are hard to find for the intermediate years?

Gas tank filler neck. The metal part that bolts to the body, that the gas cap attaches to. It's unique and not found anywhere else or reproduced. The rubber gas filler hose is available from MTS, as is the breather hose, but not the metal insert that the breather hose attaches to, which goes into the main filler neck. The gas tank skid plate is unique to this era, but the tank itself mounts directly to the frame, so the skid plate isn't essential.

Seat brackets are unique to this era and sometimes difficult to find.

Bushings for the steering column are not available, the lower one typically gets worn out and allows some slop between the shaft and the column. The columns were also used in Commandos and Postal Jeeps, with minor differences.

Windshield hinges are not reproduced (applies to all 55-75 CJ-5's and CJ6's).

Tail-light assemblies are unique to the era (not just Intermediates, but around 68-75-ish) and aren't easy to find. The lenses are available from Grote, but you have to look for them.

That's about all I can think of for the moment, but I'm sure there's more. All of the above can be worked around, there's nothing that's a deal-breaker. The wiring harness is lousy, with no fuse panel and only a couple of inline fuses protecting the circuits. A fuse panel was added in 75.

The major advantages of the Intermediates are:

Flanged and centered Dana 44 rear axle.
Large drum brakes (11x2)
Most powerful V8 engine offerings (72-73 304's were about the most powerful offered by AMC before pollution controls knocked the HP ratings way back).
Transmission tunnel cover unbolts, allowing easy access to transmission and transfer case. If you've ever had to pull the top cover off the transmission you'll appreciate this, as you don't have to drop the entire transmission to do the job.

The cover on my '75 is welded on. I've never paid attention to any other '75s, but I was kinda surprised to see that when I bought it.

Yeah, 75 was the first year of the welded cover. Up to then they were bolted on. Came in handy a couple of weeks ago on my 74 when I had to pull the cover off the transmission. About 5 minutes to pull the trans tunnel cover.

75 also had a unique transmission/transfer case cross member, it connected to the top of the frame as well as the bottom using two separate brackets on each side connected to the bottom one piece cross member. It also was the first CJ that required a catalytic converter.

Only the V8s had the catalytic convertor though.

It is more difficult to find minor parts for intermediates but most "major" drive train parts are available. With creativity and a lot of searching the internet I have found most of what I need. I have a 75 which has the first fuse panel of any CJ. The 75 also had a stouter frame compared to the other intermediates. (Advantage over the 76+ is that they are not nearly prone to rust.) The most frustrating part is finding a decent top if you don't care for the Bestop option. (Which I don't) The original top manufacturere went out of business in the mid 80's.
