Are there any date stampings on the sub frame?

[Bottom Feeder]

I have a 1970 Formula project car.  Cowl tag, vin, and title all say 1970 and real Formula.  I was just wondering if you guys know of any date stamps on the front frame.  Reason I ask is because I have a 71 Esprit and a guy was asking me about swapping some frame goodies.  I didn't know if a F body sub frame is simply just that. Thanks

Not really. Occasionally some have stampings but they don't really translate to anything useful.

IIRC there may be stampings at the rear of the frame drivers side near the angled edge. I forget if all years got them or perhaps just later ones.

'70 and '71 frames are the same AFAIK.

My 78 Project Car has the Sub Frame from a 76 Camaro....It doesn't know the difference. NOT A TA has a thread on here regarding subframe differences....

Thanks guys, I appreciate it!

The numbers are on the tail end of the passenger's side.  I haven't really made any sense out of them either.

I guess you see there are two recent threads right together on this subject.
