Can anybody tell me if all dual exhaust, 70 Mustangs, came with the exhaust cutouts, or could it also be had with the standard panel. I Think I've seen Bosses with standard valance.

Thanks

You are correct both '69 and '70 Boss's came with the standard rear panel and dual exhaust.

Ok, but were the exhuast cutouts optional? and what about the Mach 1?

as far as I know, all Mach 1's came out the back.

No on Boss's the rear valance came only as the standard valance (no cut outs) and the cut out valance was not an option. On Mach 1's the valance was either way depending on the engine choice I believe all 4 barrel cars had the cut outs but, I'm not positive.

Yeah, I've asked the same question on the Danish Mustang website and someone told me that:

In 1970 all Mach1's with 351-4v and 428 CJ came with cut out's and the rest came with standard valance, including the Bosses.
