Driveshaft question

[nbristow01]

I am getting ready to install my 5 speed. I have all the parts gathered. When I bought the 5 speed it came with a front portion of a drive shaft that has the 3 hole flange on it. The trans has the 3 hole also. My current shaft is a 4 hole. Is it a mistake for me to have the 3 hole front portion of the shaft, that came with the tranny, have it shortened and just bolt it to the rear portion of my existing shaft? Or should I keep my current shaft as a unit and have the original front portion shortened, 3 hole flange installed and use that? or does it even matter?

use the 3 hole flange, and get a new guibo. Blunt has a good price on the guibos and they are OEM, you don't want an aftermarket guibo they are softer and tend to have more flex. The flex can potentially shred the guibo as it hits surrounding areas.

as that can affect overall length of driveshaft. Don't know where you can find this info, I didn't see it in the FAQ section.

Consensus of opinion is that the 6-hole Guibo has a longer life than the 8-hole.

So, if you have your driveshaft modified with the 3-hole flange part, make sure you get the overall length using the different thickness 6-hole Guibo (as mentioned in the post above).
