does anyone knows the stock lenght of the drive line of 68 chevelle with turbo 350 where do you messure them from? thanks for info

No one knows for sure :) I heard that Chevelles are just plain weird, in that two seemingly exact same cars can have different lengths. When I did my TKO conversion, the driveshaft I got with the kit, that they always send out, was too short. They said sometimes that happens, and now they require the trans to be installed and actual measurent taken before they send it out.

Sorry, I know that response did nothing for you.
