Will any 8 3/4 fit???

$3200... Holy crap! Is it gold plated? Call Dr.Diff and get a Dana for that price. That's INSANE!

Be patient and beat the bushes. Find a 66-70 B body rear if need be. They are out there and it's not likely to fall in your lap cheap, back to beating the bushes.

Even if you paid $500 for an A body rear, I can't see where the other $2700 would come from!

How much is the E body rear? Get that, pay to have it shortened to whatever you want, probably around 150-250 depending on who does it, then buy axles from Dr. Diff, $300. Still don't see where the rest of the $3200 quote is coming from.

You'll need to buy wheels if you got SBP now.
