I have a posi unit that may be from a corvette since the year of the date code is a single digit. The gear code is FH. Can someone tell me what this code belongs to? My numbers book does not have axle codes.
I have the NCRS "Corvette Specifications Guide" which will cover most numbers for a specific generation corvette. I also have their "Technical Information Manual & Judging Guide" (TIM) that addresses a specific year, both are available from their web site. "Corvette by the Numbers" by Alan Colvin is also a good source which is available at the NCRS site or Amazon, etc.
These books are Corvette specific & don't include the other Chevy codes.
