I don't. I sold that car and gave all the receipts to the new owner. I think I looked at the Rancho site and looked for the same specs as the stock rear Nova shock with regards to compressed and extended lengths and top and bottom mount style. Had to slice the polyurethane bushing on the bottom as it was just a bit too wide for mounting. Put some oil on a very sharp knife and a few seconds later it fit.
Depends what you’re going for. I’ve run Comp Engineering three way adjustable set to 50/50 on the back for a long time. Back in the day it was my daily driver. Really depends what you want. However, these cars aren’t heavy, or complicated in that regard. Best thing is to not over think it.
