What is the correct oil drain plug for the 96 LT1? I am getting conflicting info. I know for sure 94 and 95 are 1/2" x 20 (and for many, many years before). Some sources say this is also correct for the 96. Others say it is M12 x 1.75. Perhaps it is both with a running change in the year. The parts maintenance stickey in this section only lists one part number for 94 - 96 which is probably 1/2" x 20.

95% sure it is the same as the 94-95
That's what I thought. But if you look at the Fumoto site (maker of the best no mess oil drain item), it will show a different part and bolt thread. A call to Autozone and Pep Boys and they will tell you that both part numbers (standard and metric) are correct for 96 only. 1/2" x 20 and M12 x 1.75 are not the same. What gives?

The forum was down a few days. Anyone with a 96 changed their oil lately? What size do you have?
