dana 18 in 70? you sure its not a dana20? if it is an 18 you will have to change the rearend as the diff will be offset to match up to the 18 t-case. if its a 20 then you will not have that problem. you will probably need to modify both driveshafts for length and u-joints as the 205 is a large case and probably has larger yokes than your jeep. you may have to modify the clutch linkage, what engine do you plan to use on this? a small block chev will bolt on but the stock engine will require an adapter of some sort. you would probably have an easier time putting in a t-18 from a stock jeep application, and after the cost of adapting it might come out cheaper as well.
transmission swap 3spd to SM465 ???
G
I have 3 spd with Dana 18 xfercase in my 70 CJ5. Since I have SM465 w/205 mated is it good idea to swap from 3spd w/dana18 to SM465 w/205. If so
how much of a trouble to swap-out, any modifications?

You didn't mention which engine you have. Presumably, you have the Buick 225 V6 and not the Willys F-Head I4. Anyway, the
easiest swap for the 225 and the Dana 18 would be a SM420 since the 420 has the same input bearing retainer size as the stock
Buick bell housing. You need to buy the $adapter$ for the 420 to the Dana 18.
I would guess the 465/205 combo will be too long for a CJ-5, get out the tape measure. Plus you'll have to get the bell housing
machined to fit the large 465 input bearing retainer.
The other option is get a CJ T-18 or T-98. You'll probably need to get the input bearing retainer machined down to GM size.
You should have a standard BOP/BOC bell housing now and the 3spd trans should have an adapter on it.

Have buddy that has the SM465 and Dana 300 in his CJ7, what a sweet set up!
It is a giant tranny. Like someone said, may be too long for the 5.
