Default Truck 12 bolt doable?

I have a chance to grab two 12 bolt (truck) rears for 250 bucks friday. I was going to try and convert them for my T/A by myself. I know the pinion is a little smaller but is that a big concern? Just looking to get a little info from some people about a truck rear and if this is a good idea.

Thanx
Patrick

There is a bearing so you can put a car gear into a truck housing. Good luck.

I'm also curious in this what truck rear would be strong and ideal for a 98 z28. and how hard is it to convert over. Also how would they hold up perform. Is this a bad idea. Dont mean to hijack

I have heard people say that, but have never seen the bearing. The OD of the inner bearing on a car is much larger than a the truck. The bearing ID would be almost the same as the OD to make it fit in the truck housing.

No it has leaf perches. You just grind everything off of it and weld your stuff from your rear to it. I dont mind staying with the 4.10 gears but the 3.90's would be nice

No one makes a tq arm mount for these old rears, you will need to fab one yourself.
