Logan's metals will make you a custom stainless steel.
check with this guy i think he's got the connection to them still. be sure you studdy the cad drawings they send you carefully. my dash came out 99% perfect within about an 1/8" on everything one or two holes were an 1/8" off but they were to the nats ass when i re studied thier drawings.
They do do a pre 75 dash we had one done for my buddy by them.
