Rear Centerline
 

My frame has been bare since I've had it so I've never seen the diff bolted on. Therefore I don't have anything to reference the centerline for the rear. Does anyone have a measurement from say the end of the rear frame rails or some other reference point? If not that, i could use the wheelbase length of a 67 C10 SB Fleetside. I could use that to measure from front to rear. I am in the beginning stages of installing a Wideride and a Fatbar setup and am at a standstill without some reference measurement. I have searched and not found this info anywhere. I'm guessing centerline is somewhere just short of the bumpstop brackets but some of you guys that have done this would certainly know better than me. Thanks in advance. I will get some progress pics up as soon as I have enough progress to post.
