[nw] NC: 2.9X posi IRS pumpking donor/halfshaft q?

[Don Berry]

What about the front drive shaft from a 4x4 truck. I'm sure that the 1 ton
stuff would be heavy enough.

I know this is NC but I'm just amazed at some feedback/backgrounds members
can relate back so here goes. (plus I know theirs several owners of
possible donors on these lists)

A fella from Detroit called me up this eve. on a net tip from a friend that
I'd checked out swapping a 'vette posi into a Datsun Z car.  Neat to hear
his name when he intro'd as I knew it immediately as a fella that had a
gorgeous older Z in Hotrod a year ago April or May as an import w/ domestic
muscle feature.  Anyhow, we were trying to figure out how one could
fabricate 'telescoping' halfshaft for such a swap (he thought I'd solved
this but it hadn't even occurred to me yet).  Vette's (I'm not v. familiar
w/ their setup) have fixed length halfshafts and our Z's all have
compressible telescoping  halfshafts and he hasn't been able to find a shop
that has a clue on fabricating anything similar.  Anyone w/ ideers on this
one?  He also mentioned that a Viper rear end looked a lot easier to
transplant d/2 it's OEM dimensions ('vette unit needs narrowing etc he
said) but he only found one locally available for big bucks.  I've got nil
exposure to other makes etc but thought some BMW's or Mercedes (or any
other) might have feasible donor diff's for this swap as well??  Basically
he's looking for an ~8.25" or larger ring gear posi pumpkin w/ low ratios
(~3 or even less).  He said the viper ratio is 3.07, no ideer if other
ratios were available?  Dana 60 'vette units only go down to 3.07 and he's
at 3.15 know so that's not much gain for him but he's still interested in
that step if it's all that's available.

So any ideas/thoughts at all on the halfshaft fabrication (other donor
telescoping parts? our Z ones are too weak for him), other donor diffs w/
any ratios, and lastly any sources for the viper rear's or others suggested
w/ any ~ costs would be great.  He's not on the 'net so I want to
accumulate what I can before phoning back etc.

PS he runs high 10's in the 1/4 in street trim w/ A/C and a fully insulated
booming slick car that weighs in at 2600lbs wet w/ no driver that also sees
track roadracing several times a year.  A seriously cool ride I hope to see
in person some day.  Just trying to spread the fun .
