Hi 71,
NEW car... NEW member. WELCOME!!!!
Your convertible looks very nice in your picture.
If you're going to be doing some work on your car I'd like to suggest 2 books that I think you'll find very helpful and worth their cost.
First is the Assembly Instruction Manual (AIM). This book of engineering drawings was used on the production line by the workers. There's one for each year of production.
Second is the GM Chassis Service Manual. This is the book that the service departments at the dealerships used. Again, there's one for each year of production.
Many of the larger Corvette parts venders carry them.
Good Luck with your 71!
Regards,
Alan

Good advice from Alan who is very knowledgeable. I also have the 1968-1969 Corvette Technical Information Manual & Judging Guide and assume that there is one for 1971. I use it all the time. Numbers cast on to the housing of your transmission will lead you to what type of tranny you have. Likely options would be Muncie, either M-20 wide range 2.52:1 ratio or the more probable M-21 close range 2.20:1 ratio. Long shot could be the ever famous "Rock Crusher" Muncie M-22 2.20:1 but I think those were usually paired with big blocks (more horsepower). The M-22's typically have a fill plug about 1/2 way up on the side of the housing and a drain plug at the bottom of the housing to make chaning fluid real easy since these were real popular with drag and track racing back in the day.
