I went about things a little diff due to not wanting the fiberglass cover. I bought the shifter w/ metal cover from Tom's plus the shift rods were already cut for my six cylinder. Bought the offset shift handle from Duff's to match his T- case shifter. I cut the hole large so cover would just fit to give me more room for access should I need to get to the shifter again easy and screwed down with 1/4" hex head sheet metal screws. Either way, simple install, I just hate fiberglass.
