69 Charger frame rail specs??

[John69Charger]

Quick question for someone on here a little more familiar with mopar restorations. Upon mocking up my new front frame rails, factory specs say outside to outside measurement should be 36 1/2", however in order to bolt the k-member to the rails im getting a measuremnt of 36 1/8. Wondering if that would be considered within an "acceptable tolerance." ( i think a read somewhere, within 1/4" was acceptable)
thanks for any input, cheers

Thanks, that looks a little more technical than the diagram i have. My center of gauge hole to gauge hole measurement is pretty much exactly that (33.92), so i guess im fine then. Just the outside measurement that is off a little. Possibly due to the aftermarket rails i suppose.
Thanks again

Wondering if you would have a picture of where is describes what each point is (A,B,C,D etc)
also is that from an owners manual?
thanks
