5 speed Driveshaft length

[jrhone]

Doing a 5 speed conversion and I found a driveshaft from a car that had 245 5 speed in it. I want to verify the length that it should be before I buy. What’s the length that it should be flange to flange?

Depends...3 bolt or 4 bolt?

[jrhone]

Sorry. 4 bolt.

59.25” if memory serves

59.75" appears to be the length, however, if you search the forum you will see several differences. You won't know exactly what length you need until the 5 spd box is in and you can measure.

The diff can be moved backward or forward a small amount to compensate for slight variations in length--the rear sub frame diff holes are slotted to allow this, as is the center bearing mount carrier. That said, I'd want to measure my own application before ordering any driveshaft. --Fred

Thanks guys!

Yep..you must measure. Dont go by someone elses #'s

[02tradition]

Well let me put it this way. 59.25” for 4 bolt and 59.75” for 3 bolt. To compensate for the difference in thickness of the guibo. There is enough adjustment like previous people have said in the diff and center bearing. Been using these numbers for years no problemo.

Thanks guys!

Not to highjack the conversation but does anyone know what the length would be on a 260 5spd drive shaft. I have both drive shafts 3 and 4

Not sure but would be nice to know if anyone on here knew. I know getrag 245 on the M20 is about 56.5” and getrag 240 on M10 is about 62”.  It mostly comes down to what M20 motor mounts you are using,  some put the motor closer to the firewall than others. 

 

Edit :  my measurements are flange to flange. NOT to the tip of the nose
