Do NOT pound in, use your bolts or threaded rod to install, material is brittle and misalignment is not forgiving, spindle bushings are too big on the outside, putting them into clean sanded spindle tubes made my steering way too tight
I bought a Kimpex kit first, had to sand every one of them to make them fit. Some of them the lip even cracked and broke off on install. I bought the SPI kit and right away I could tell the quality was much better. Had no problems installing the SPI kit, and not one of the lips broke off. Much better kit in my opinion than the Kimpex. I'd recommend SPI kit to anyone looking for this bushing kit for their machine!
