Pair of the weld yourself spring under ubolt plates RuffStuff sells for Ford F-150. Welded by the guy I bought them from, who determined they do not work for 1st Gen Nissan Xterra - I determined they do not work for 2nd Gen Xterras. Not sure what else they might fit besides the f150. Ruffstuff sells for $60 unwelded, these are welded and I’ll do $60 shipped anywhere USPS will do a flat rate box for.
