Does anyone out there have or know where to find the distance from the rear axle center line to the front spindel centerline?

I'm looking for measurements for a 68 Camaro

108" wheelbase

Thanks

keep in mind that the actual wheelbase measurement will vary a little bit depending on where the caster is set. if the spindle is tilted back, the wheelbase is shorter. if it is tilted more forward, then the wheelbase is longer. sure, the total difference might only be 1/4", but it is still a difference.
if you are trying to line up the subframe or something like that, there are other measuring points just for that.
