[QUOTE="Walt Jaquith, post: 425272, member: 18654"] Point of no return: The 4.0 motor mounts are history. Had to remove the front brake lines and the steering shaft to get enough room to take the left mount clean. Since the brake lines are opened up, I'm thinking about doing the master cylinder/booster upgrade while I'm at it. Decisions... Also, test fit on the transmission. There's lots of room. I've got the thing positioned exactly where the original T-case sat, the plan being to not have to mod the drivelines. But I could come forward with the whole package and improve my rear driveline angle. Not sure it's worth it; the old one had a little more angle on it than I like, but was working fine. Decisions... I'd like to make a real rear cross member instead of bolting the tranny to the skid plate like cheap...I mean Jeep did it. The 4x4 version of the stock 700R4 rear transmission mount hangs down too far for that, so if I do it I'm going to have to go completely rogue and scratch-build something with a completely different mount. That's a lot of work, but I want the job done right. Decisions...[ATTACH type="full"]115761[/ATTACH] [/QUOTE]
