Front Driveshaft Clearance w/AMC304/TH400/Dana300

I recently installed my drivetrain and as it says in the subj, I mated a my AMC304/TH400 to a Dana 300 w/an Novak Adaptor kit. This put the transfer case a couple of inches further to the rear so now I have to modify my driveshafts. But I also found that the front d/s no longer clears the stock exhaust y-pipe. Has anyone else run this setup and what did you do to clear the front d/s. Just looking for different options. Thanks,

Hey,

I have a 305/th400/d20 in my cj. I have the same problem under extreme flexing. I had my muffler shop build a yj pipe and he flattened that area out a little for more room.

I plan on raising the drivetrain up a few inches very soon. That should fix that problem since there would be more of an angle for the shaft.

Let me know what you do..

Yeah I could raise the xfer case/trans skidplate up an inch (I have a 1" drop now) but I'd be afraid it'll create too large of an angle for the rear d/s w/out a cv joint. Most likely I'll have to reroute the exhaust. A poster on JU says he's seen it routed all the way forward around the front of the engine. When I get back to this project I'll have to crawl under there and map something out. I'll post the results, but it may be a while. Thanks,

I have the same problem. My Y pipe looks like it got hit with a cannon full of little rocks. My fix will be to route the exhaust forward, then over, then back. Yeh it wont breath real well that way cause of all the bends. But it cant go overtop of the shaft and to make it lower it would be the lowest part of the jeep. I think z50k2 may have done that exhaust routing. Do a search on his screen name.

Here's a link I got off another board for the exhaust routing:

Looks like a nice clean install, don't know if a "kit" was ever developed.
