Drive Shaft Options

I don't know I bought the car and with the car I got a 727, 8.75, headers, exhaust, floor shifter (minus torque shaft), 73+ front end, 489 case, gears and sure grip. He offered me all of the spare parts he had with the car (for more money than I paid) but I don't have room for 2 cars in my garage lol.

Yea that is why I asked about strange engineering DS and or using another shop. Dans said it would be close to 100 to shorten my shaft.

Gotcha on the 7.25 to 8.75.
Just so you know, I had the trans yoke but had the shop replace or build everything else.
This new shaft is 7290 Ujoint DOM steel, guaranteed for up to 600hp and was about $380.
