2wd trans swap

[12valve350]

Ok, So it's been some time since ive checked the threads out, And ive read up on a few different swaps but i still have some questions about what id like to do. Iv'e got a 1990 D350 with the stock 727 and the 3.07 rear end. Im tired of that slippy thing and i was wondering how much it would take to switch it to a 5 speed. Most of the swap threads are for 4wd trucks which I dont have. Would it be easier to do? what all do i need? Any help would be greatly appreciated!

It's actually somewhat harder, but only by the reasoning that you need to change the floor tunnel out.
You'd need the crossmember and isolator system from an early truck (1989-1991), but the later system will work in the earlier truck, too.

Pre-1992 Getrag 5 speed is it's own crossmember, but 1992/1993 was a mix of the old and the new and used the automatic crossmember and isolator.

I outlined some of the differences in a posting over on DTR a while back:
