Help on 84 CJ7 Restore

Post #1 - Yes I am a Noob here and as well as with restoring Jeeps so any help would be very appreciated!

I just aquired an 84 CJ7 with a bad 258 but a good T5, I also have a CJ5 with a good 304 and a bad tranny. My question is: Can I use the T5 with the 304? if so what do you recommend that I will need to do so?

Also is mixing fiberglass and steel body parts a bad thing?

Thanks
Feenix

what tranny does the 304 have behind it? All Cj trannies from the 80 have the same size input and output shafts so if it is fro the 80's it should work.


You should be able to take the 304, the bellhousing and t-5 that was behind the 258, and it will all bolt together.

there is nothing wrong with mixing glass and metal. YOu might be thinking of mixing aluminum and metal. That sometimes creates a chemical reaction that screws up the aluminum...at least thats what i hear.

You might want to look into that before you put the T5 behind your 304. It is the weakest tranny that jeep used in the CJ's. I have it behind my 258 with no problems SO FAR, but most people seem to suggest an upgrade to a stronger transmission. I plan to upgrade mine when it breaks. Try this site for some info:

Actually the SR-4 and Peugot trannies were the weakest, but the T-5 ain't far behind... It's basically a T-4 with an overdrive 5th.

Slight correction...

<All Cj trannies from the 80 have the same size input and output shafts>

This is true between the 258 and 304. However, the 151 and 150 used different input shaft size and spline count...

I am not sure what tranny is behind the 304, all I know is that it needs work unlike the T5 I have.
The CJ5 that I am pulling the 304 out of is from either the mid or late 70's. So do you guys think I might have a problem with that configuration.

T-5 is a bad idea for the 304. From experience it will not hold. Search for a T-150 three speed or a T-176 four speed which both were factory matches for the 304. I had one of each and never broke anything. Now I'm running a T-18 behind a 360. T-18 is plenty strong with great ratio span, but takes some research to make work.

Okay, my new problem has to do with the engine mounts for the 304 to fit in my 84 CJ7 frame. I know MORE makes a heavy duty mount for this, but $230. Anyone know of a cheaper one or have another idea?

Use the motor mounts from the engine donor jeep.

I was thinking of that but will the mounts out of a 73 CJ5 Frame be the right size to put it in my 84 CJ7?
