The U-P parts are Hit or miss, (Quality & fitment) most recent Tac strip, all the wood required hours of fitment , I try to source FoMoCo parts.There are close but differences.The Metal gauge is One size thinner then FoMoCo,
Between Two others & I working on 7 steel 32s. We have purchased every part U-P makes except fenders and running boards .Are the U-P fenders drilled?
Brookville are not , quite a bit of fitment required . I have seen three sets others I know have purchased, between 13 32s, same with at least with the Brookville roadster parks (fitment issues and differences) then FoMoCo
