(68 dart 340) I am swapping 7.25 to 8.75. I bought correct A-body housing and axles staying with the 5x4 sbp so my cragers still fit. Problem is my old 7.25 backer plate wont fit due to wrong bolt patter and center hole to small for axle bearing to fit though hole in middle of plate. I do have a set of older backer-plates that I had on a donor 8.75 that fit fine but have NO shoes,springs, or drums. My question is how do I figure out what size drum i need to buy to fit these and will it have sbp on it and how to I measure the one spring that was stuck on backerplate to figure out what size to buy. I can take pics of what i have if needed.
thanks
