Finally Early A Body Shorty HEADERS

I just bought a set of the big 2 1/4 Dakota logs (91-92 only) and slapped them on a long block. Anyone got a tape to measure how wide the early A fenderwells are? Mine are out so I cant get a measurement. These are:
26" at their widest,
are flush with the back drivers side trans plane and
extend 4" past the passenger side trans plane 2" below the lower corner of the head
2 3/4 inch thick off exhaust port plane at steering shaft area
extend 1/4 (if that, and you can fanagle that with a shim under the mount) under head parting line under the 3/5 ports for steering gear clearance.

My motor is on a stand so I cant get interference measurements from the manual steering box but I have seen these on a 65 and they fit his. The one part I see a potential snag is the passenger kick back toward the firewall, may have to dimple it or trim the exhaust flange coupler as its pretty big (newer 1 7/8 models may be smaller here). Hoping they would fit as they are easily better and cheaper and more plentiful than the original design, and supposed to flow better combined than the Hi-po 340's.
