This kit features two eyelet mount conversions for you NG900 and OG9-3.
A 10mm through bolt with a captive nut and a 1.25” spread makes it possible to use modern performance shocks as well as inverted coil-over setups. Misalignment spacers are needed for your specific application.
Three bolt holes and contour matched shape distributes load more broadly across the shock tower. And, the 3/16” plate thickness makes the kit very strong.
