What, if any, is the difference? I see them listed seperately on some websites. I accidentally ordered 2wd and hope they will work. Thanks.

My 2000 z71 came with 2" blocks.

nbs 2wd didn't come with any blocks...they'll fit fine as long as they come with new u-bolts

cool thanks. I have plenty of u bolt. When I did the 3 inch block I left all the extra bolt. Didn't cut the excess off just in case I wanted to go up to 4".
