I meant is the clutch linkage mechanical or hydraulic, thanks for the reply, I'll start looking for a donor.tgreese wrote:In FSJs, Jeep makes up the difference between the length of the 258 and the V8s with a spacer/adapter between the engine and transmission. This makes the manual transmission input shaft very long in these V8 FSJs. This topic has been covered ad nauseam in the forums if you search.
Wagoneer and J-trucks are the same in this respect. Baby Jeeps 1971-1976 got the close ratio T-18, which is probably not what you want. The 258 FSJ T-18s are short input, like the close ratio CJ transmission, but wide ratio. With a short input and V8, your shifter will come up under the dash.
Find a V8 J-truck or Wagoneer donor and take everything you need. Yes it will all bolt in. Or just buy that Jeep and sell your '73.
What's a z-bar? It's just a clutch, 11" Borg&Beck type for the 360 and 401.
Does the clutch bellcrank mount in the same location as the auto trans linkage, if so would you think a cj bellcrank and linkage kit would work? I'm starting to put a list together, got a lead on a trans, waiting for reply from seller.tgreese wrote:Ah, mechanical. Possible it was cable for a year, but I don't think so.
I'm not saying they will be a direct fit, as long as I can get them to work with some modification. I don't expect to find all the parts I need from the same person the cj stuff is cheap and available is what I mean. Yes a donor truck would be nice but J series are few and far between in FL I'm not paying for a nice one. I want to keep this one.tgreese wrote:My reaction - sorry if I seem impertinent, but why would you think the CJ parts would fit? All different, AFAIK. Principle is the same, but the measurements are all significantly different.
If you can get a complete FSJ donor, you can pick from the donor what you need at your leisure. Then sell off what's left over. Unlikely anyone will have a complete list of all the parts you'll need from the donor.
Much simpler to pay a premium price for the Jeep you want (a 4-speed J-truck) and sell the automatic truck to someone that wants it. JMO.
Well I found a j20 t18 complete with d20. Ya I figure the linkage is going to be a nightmare, I found a few used pedal assemblies on line, I think I could remove my brake pedal and swap in the clutch/brake combo while leaving the bracket alone. I'm still waiting on a response from the seller of the trans, you know how that goes...tgreese wrote:I expect the place where you need a donor the most will be the pedals. I expect dimensions of the CJ parts will be way off here, though the design and components are similar. Possible you could go the hot rod route and adapt an aftermarket pedal set to the truck. Without the factory linkage, I'd expect a hydraulic clutch would be easier since you would not have to figure out the proper linkage and bellcrank geometry without a factory example. I have not measured the linkage, but the rods are definitely different, and I'd expect the bellcrank to be longer in the J-truck due to the wider chassis. You can use a short input T-18 (or one of several other truck 4-speeds) if you can accept the shifter placement. Some have let the stalk come up under the dash, then heated and bent the stalk into a dog leg so that it's reachable. Not how Jeep did it, but workable.
The factory parts manual might help you to see the pieces you'll need. The '74-80 parts book is available on CD-ROM for less than $25 from RockAuto. The '62-73 parts bool is on the Tom Collins site, but this book seems pretty sparse wrt illustrations, and your possible donors more directly overlap the '74-80 book.
Ok, I'll take a look, so did you give up on the manual swap?carnuck wrote:I have the pedals in my for-sale stuff but I had planned to do a 5 speed swap (avoid the T5 though. It’s too weak for V8s. My 6 killed a stick one in the driveway!)
I was almost done an AX-15 swap for the first Ouray invasion but UPS lost my steering knuckles.

My back gave up on manual transmissions after the rollover 2 years ago in my Comanche when I was run off the road.
