Post will this rear axle fit my AD / spring selection

I got an axle out of a 1990 fullsize blazer, and I'm wondering how that thing will fit on my 1950 chevy truck?

also, if I were to get springs from a junk yard vehicle what vehicle should I be looking for? I'm planning on going with a TCI crossmember that will be lowered, but not slamed.

It depends on how wide the rear end is. Anything in the 60"-63" will work well without any odd ball wheel back spacing. The best width is 62" mounting surface to mounting surface. Mid 70's Camaros and Firebirds are a perfect fit.

Now for your springs. Couple of choices. I used mid 80's Chrysler minivan springs for my '53 AD and they were a breeze to install. Cost about $50 at the wrecking yard and they come with bolt on hangers. If you would like to see how I did mine there are pics on my site (link below). This is a good option if you have some basic welding skills since you'll need to fab a mounting bracket on the outside of the frame to mount the front spring bracket. (see my comments below about AD non-parallel stock springs.)

Your other choice is to purchase a set of aftermarket springs and hangers. Most of these use Dodge truck front springs with pre fabricated hangers. There are several suppliers for this setup, RB's Automotive comes to mind at the moment. This is a more expensive way to go though, (somewhere in the $200-$400 range).

One more thing to think about is that the rear frame on the AD trucks gets wider as it goes towards the rear. If you look at the stock springs from the rear you will see that they aren't parallel. This equated to a not so smooth ride since parallel springs work best when mounted parallel. Make sure if you buy a kit that it mounts the springs correctly or your ride will definitely suffer.

Good luck whichever way you go.
