69 firebird rearend question

[RBR]

Got a 69 bird that came with a 250 motor and 3 speed manual on the floor. I have an aftermarket front clip and now hunting for a new rearend. Mine is a 8.2, I'm looking to up grade. I got one quote for $2200 before shipping and taxes, its for a moser 12bolt complete. Is there anyone in the bayarea CA, that I can go to to get some more qoutes from? My plan is to run a GM motor with<450hp. Thanks in advance. Dennis
