1) Do the upper and lower bushings match stock C10 spindle?
-no, our control arms use Delrin self lubricating bushings, so you cannot use OE bushings.

2) Will your arms work with the stock 73-87 spindles?
Yes, the difference is in the ball joint. We select the ball joints based on the platform year you order. If you are using spindles from a year other than the trucks manufacture date just let us know what year the spindles came from and we'll match it up.

3) Is it correct the $1400 kit does not include the coilover shocks?
That is correct. As we offer many different shock options it's best to sell the two separately. This allows you to choose whatever shock option is best for your build.

4) Is it possible to buy the upper bracket alone if we already have arms, and if so, what would be the cost?
The upper bracket is not available separately as the shock length is critical. So you need to use our new arms to make sure the dimensions are correct.
