I read the other reviews for this product and saw there were a few problems with the bolt holes being too small.Didn't have that problem and it went together very well, one issue I did have was the side supports are kinda hard to get parallel with the floor braces, I fixed that with a square and tightened the bolts snug, adjusted them a bit to be sure they were straight then tightened them down the rest of the way.First job was pressing out the rubber bushings on a set of new leaf springs to install poly bushings, took a lot of pressure but they came out.All in all I'm quite happy with this product and would recommend it, it's fine for the do-it-youself home mechanic.
