When I installed a wrangler tub on my CJ frame I used 1 inch lift body mounts. I'm almost to the part where I reinstall the clutch linkage. (It's the rods and bellcrank style) Am I going to run into any problems caused by the 1 inch of body lift?
YES, one side pivots on the bracket at the bellbousing. The other side pivots on a bracket attached to the body (now 1 inch higher) so you can try to lower this body bracket, but then the rod going through the firewall will be too short. You can cut it and weld in a section to make up the difference. OR do the switch to a hydraulic set up. Not the internal throwout bearing kind that leak all inthe clutch, but the one used on many YJ's and 4 cyl CJ's.
Switching to the hydraulic was my first idea. Because I went over it all in my head and came up with the same hurdles you did. When I tried to bolt the master to the firewall the brake booster was in the way. I should have stuck with manual brakes.
I used the booster for my CJ application but with power brakes. I odered the clutch master for the early 80s CJ with 4 cylinder. Do you have the hydraulic? I'd love to see pics of how it's done. I know that the wrangler uses a clutch master cyl. with the resovoir mounted separately.
I'm about to do the hydraulic swap myself. I have all the parts, just waiting till my worn clutch goes so I can do all of it at once. I was lucky. I stumbled across a 4 cyl CJ-8 in a junkyard and got the whole set up (minus the small heatsheild on the slave). I even got the correct swing pedal so I don't have to cut/weld/and fab my old one. I'm running stock power brakes and my firewall has the indent / pre cut out of where the clutch master goes. Although I haven't made the hole yet, there is room when I put the part in place and check for clearance. My brake booster is set off the firewall some 5 to 6 inches with the swing arm bracket. The clutch master goes beside that. I believe it's the same type of set up used in the YJ (your tub should be the same) The master I got out a the junk o yard looks to be the same as the ones sold in the 4x4 catalogs. ( the yj uses 3 different kinds: 87 to 90, 91 to 93 and 94 to95 while the CJ uses the same part for all 4 and 6 cyl. models. *One more for the AMC vs Chrysler debate)
