Any tips on getting the forward section of the prop shaft bolted to the guibo? I'm having a hard time convincing the bolts to slip thru the yoke.
Do you have a large hose clamp slightly tightened around the perimeter of the giubo, like the one shown in my photo? That allows you to bring the holes of the prop yoke and gearbox spider into alignment with the ones in the giubo at the same time.

I do... but to be clear the steel strap the guibo came with is still in place...

One of the nice things about the Paul Spruel flex disc is it does not have to be clamped. Mine has been on and off about 6 times in the past year and I am grateful for that feature.

Yes, but the clamp arrangement that Norseman50 shows works better. You need to adjust the amount of compression on the giubo fairly precisely to get the bolts to slip in and out. I doubt that the factory-supplied steel strap is sized properly relative to the production tolerances of giubos. With hose clamps you can tighten - loosen until things go together.

Adjusting the strap that was supplied did the trick - it was slipping off the donut in the spot that was giving me trouble. Thanks for the tips guys, driveshaft is getting there.

Are the splines at the joint in the shaft indexed in any way? They seem to want to mate in only one orientation, which would be handy.

Are you referring to the splined joint between the fore and aft prop shaft sections? If so, the answer is yes. There should be some arrows or markings near the spline connections of both pieces that need to be lined up during assembly. This is to ensure that the U-joints in each section are properly oriented to each other and the assembly is in balance.

Yes that's exactly what I was asking about thanks. What do the yoke locknuts measure on the flats I treated mine to six new nuts and a 19 mm socket doesn't clear the front section of the shaftName:  Image1475333354.621988.jpg

Try using a standard, or thin-walled socket (like the chrome HF one I'm using in the photo in post #28). The black anodized one shown in your photo is an "impact" socket, designed for use with an impact gun, and by design it has a much thicker wall and may interfere in tight-clearance applications.

Is there exactly one position the splined joint will mate at?

That seems to be the case - but when I assemble the F/R sections I'm seeing the U joints "phased" opposite what this diagram shows - the "inner" and "outer" flanges are 180 out of sync.

EDIT: I get it now. I was originally asking if the splines only mate in one position since mine are a bit hard to mate. I now see they are adjustable and I can clock the flanges as they're supposed to be.

AFA tightening the guibo nuts,should the strap be taken off before tightening? Also,I've heard that removing the strap,leaving the nuts a little loose(finger tight?)and then running the car(rear wheels off the ground)will help center the guibo.Any truth to that?
