Your drums are 46-48 so your hubs are also.Your backing plates are 39-42 as are the brakes.All are mounted on 32-34 spindles.You must have spacer rings to adapt all that to your spindles I presume. I would replace both front wheel cylinders if you can find quality ones. Rock Auto has the wheel cyl kits for a bit more than $4 if your cyls are rebuildable.
