Cowl/Firewall to Inner Fender Measurements

[1973CudaKJH]

Help please. I need the cowl/firewall to inner fender measurements for a 73 Cuda. Is 7-1/8" correct for outside edge of cowl to inner fender as illustrated in Cuda4 ( I saw in an earlier post)? Is 48-1/2" where the inside edge to inside edge of inner fender is supposed to be as illustrated in Cuda1 and Cuda2?
I didn't do any other cutting/replacement in inner fender, shock tower or radiator support (Cuda3).

I tried forum search but not much luck.

I had to replace every floor, cowl, & right rocker panel. I'm getting close to hanging doors and front fenders to align up rear quarter panels. Been challenging year, but hope to have body ready to put on Schwartz Chassis this summer.

Thanks so much.

I thought I had some before measurements as well - but looking back on my notes I aligned it all around the hood width and checked for square.
Worked out well but ended up a little tight on the hood length passenger side

Thanks for help. I believe I got enough information to confidently start welding inner fenders up to firewall & cowl.
