I have a 3 speed, open driveshaft transmission with the "old style" bell hsg bolt pattern. The input shaft has 10 tooth and output has 16 teeth. I/O gear ratios are as follows: 1:1, 1.75:1, 2.75:1, reverse 3:1. The transmission was bought to update a '37 chev drivetrain, but the project got cancelled. It is in very good condition, always stored inside, and will be up for sale here as soon as it is identified. Thanks in advance for any info.
