real axel center of tub?

[itsmike2k]

Does anyone know if the stock rear axel wheel mounting surface on a 72 ends up in the center of the tub of a short wide? If not does anyone know wher i can get some dims, Like inside tub to tub and inner lip to lip on a bed. I dont have a bed yet or i would take the measurement myself. I'm really trying to figure out what BS i should order my wheels to fill the tubs.. It seems like 5" on 10's is popular, Just wonder if that puts the wheel directly in the center of the tub or not? Thnaks for any input..
