blocks/AAL

[shackwrrr]

willl the blocks and AAL off of lets say a full size blazer fit my j20??? my neigbor has a brand new set of blocks and ubolts for 20 bucks and i wanted to know if i should nab them or not?? what is the width of our leaf springs ??? i wanted to know because i want to buy some AALs for a full size chev and put them in the front to go with the rear blocks?

Rear blocks from a FS chevy will work fine. FSJ's have thr same width rear springs as Chevy's. 2.5"

The u-bolts wont work though (different axle tube diameters)

What size blocks? If they are 4" blocks, you will need lift springs up front, an AAL will only give you like 2" of lift.

EDIT: if you go AAL up front, you will want to get them for an FSJ, as GM front springs are different than front FSJ springs (our springs have more arch).

Yep. I didn't even think of that.

You will have to buy some new ones.

Any of the chain stores should be able to order you up a set. Auto-Zone ordered me a pair of TrailMaster 3" front aal's (I think that was the brand) for about $80.

IMHO:

If they are the aluminum blocks, especially the kind that you get from the big chain auto parts places and such, I would pass on them. These seem to fail fairly quickly, and only run about $30 a set anyway.
