I have a 6 cyl with discs up front with 5 lugs but drums in the back with only 4. I'm wondering if I can get 5 lug drums for the 6 cyl. I know they're available for 8 cyl engines but are there any for 6 cyl...or are the 6 cyl drums and the 8 cyl drums the same?
Looks like you are going to be back at square one then, considering swapping the 6 for an 8 again I mean, if you have to swap the rear still. You really don't need discs anyway, I'd go back to drums in the front, sell the disc's for some resto cash and continue to beef up the six if it were me. Of course the down side is that they have few rim options for a 4 bolt though.
