Recommended posi rear end?

Hey Kramer,
Just keep an eye on craig's list and one will come up if your looking just like the 340/360 your looking for . I picked up a nice A body 8 1/4 off craig's for $125 . The guy was swapping out for an 8 3/4 his buddy had sitting around.
Keep an eye out for a whole car with motor/trans/rear end /radiator ect in good shape. Maybe a car that has a lot of rust or wrecked ? It would be a lot cheaper than buying ever thing separate.
That's what I did on my 69 319 K member disc brakes , power brakes, power steering , 22" radiator, drive shaft, rear end 7 1/4 large bolt pattern till I have the $$ to make my 81/4 a suregrip ? It would make a lot of sence to do it this way instead of peice meal unless you have unlimited funds or don't mind if your car won't be running for a while? Good luck with your project and email me if you have any questions .
