Hello all,

I am trying to find out what the rear sub frame upper and lower suspension pick up point dimensions, center to center are. I know with the lowers being slotted present a bit of problem, but center to center on the slot is fine.

Thanking you in advance,
Reg Grant

I have an original rear sub-frame out of car empty.

End of slot front most slots is 19 5/8 inches.

End of slot rear most slots is 19 5/8 inches.

The upper actual bolt holes with a measuring tape is a no can do. I measured from edge of clearance hole (outer most holes) to edge of clearance hole front & rear

Edge of clearance hole to edge of clearance hole front is 30 3/8 inch.

Edge of clearance hole to edge of clearance hole rear is 30 3/8 inch.

If you would like the actual measurement of bolt hole to bolt hole I would need to install some bolts & make a cheap & dirty measurement caliper.

Dave Wheeler at AdvancedAutoSports will know these dimensions & he has a rear sub-frame checker for $20.00.
