got vn diff to suit fc holden sedan, what u bolts do i use to suit with original reset springs?
I used EH but if you measure the diff and go to your spare parts shop you should be able to buy new U bolts at the size you need .......FC427......
any other hints?
the vn diff housing tubes are the same size as fc diff tubes have done this conversion myself, ivé put welder lowering blocks used longer d shackles regards Glenn ;) ;)
