Looks like 32 3/4". Thanks guys.
FWIW: That looks to me like that dimension is rad hole to body mount hole.
Correct. The first firewall mount hole is the 3/8" hole 2 1/2" in front of the 1/2" hole which is used to adjust the cowl and door to the B pillar.
Thanks JSeery, I became computer challenged when I was forced into Windows 10. Never had this trouble before with editing and even finding where the heck stuff is.
