The Stovebolt Site Forums The Shop Area Driveline 55 1st series driveshaft lenght?

so i have a 53 1/2 ton suburban that has a 56 235 but still has the torque tube.

im planing on swaping the third member from a 58 chevy 1/2 ton.

i will be using a muncie m318 for now till i get my 319 working.

so...question 1. will my drive shaft be the same lenght as a 55 1st series?

and question 2, if so whats the lenght of that drive shaft? or about what lenght should i find. im trying to get every thing together before hand so its not down for too long, shes my daily driver.
