Same old question - Which 5 speed?

[bw4sale]

I've been exploring 5 speed options and read several threads about it, but am still undecided what I need to do.

So, today browsing CL I ran across these two trans.

1) An ax15 out of a '97 Jeep Wrangler. Newly rebuilt and never installed.$500 I know it requires an almost $300 adapter on the front side. What about using this trans in a 2wd set up?

2) An NV3500 out of an '89 GMC. 150,000 miles with new clutch kit and slave cylinder. $450

This would be going in a 2wd '68 SWB with a mild 350. Thoughts? Either one sound like a deal?

Thanks.
