Ok guys i need a little input . ive read differnt post saying to drill out the rivit
on the rad suport for the sway bar mounts .and i saw the one alan did and said
his didnt need to be drilled i don't remember . the mounts are from an 70 model truck along with the lower aframe with the holes all ready there / this is going on my 65 short step . sorry for being long winded. but just wanted to double check brfore grinding and drilling .

Thanks for your time
