Speedo cable part number 73 MT

[Charles P.]

The 73 AIM lists part number 6477901 as the speedometer cable asm part number for a manual transmission 1973 corvette. I believe the MT had a one piece cable.

The GM corvette parts and illustration catalog (from 1982) lists several part numbers but not the above number. It lists a screw on 57-73 #25032278 and one snap on 57-73 #25032096 (m20, m21). I believe the snap on refers to the attachment at the speedometer with a clip which this does.

It also lists a 57-73 #6480375 cable w/ casing 92-1/2" and 57-73 #6480373 cable w/ casing 1476.5MM.

Anyone know which if any of the above PN's if any should I be using/cross referencing from?

These speedo cable applications are VERY poorly cataloged in the P&A catalog. My recommendation on these is to purchase the one you need by application from Dr. Rebuild. The good doctor has got all these figured out and, if there is a current Delco replacement available, he usually has it in stock.
