Got my SM420 in Friday. 3-Speed bellhousing and flywheel, AA adaptor (4.5"), etc. (Thanks Lance)! <IMG SRC="smilies/bounce.gif" border="0">

Can I use my stock rear driveshaft if I reverse my rear springs (su): 10.5" SM420 + 4.5" adaptor = +3"; same as 3" + gained by reversing springs??? I've got new 4" softride springs coming next week and I run 2.5" Confer lift shackles... Anyone ever done it this way? If so, what type of articulation could you get sprung under without losing the shaft???

I have to reverse the springs anyways to fit my new Boggers (16/35), but don't have the rest of the money to finish the SM420 conversion (transfer case rebuild and lengthen driveshafts).

I'd hate to have to lengthen the rear shaft twice. What's the going rate for a custom shaft with tons of slip?

Sorry for the long message. Any input greatly appreciated.

It sounds like a good idea. Flip the dam springs. See how well it mocks up. It is always reversable. And you will still have to lengthen the front driveshaft. Remember that shortening a driveshaft is a heck of a lot cheaper than lengthening a driveshaft

Unless you do a Shackle reversal in the front there is no real reason to get a long travel driveshaft. I get reasonable flex and am still running the stock diveshafts.
