Help with front Dana 60 pinion angle / binding

[sw99]

1986 Chevy K30 one ton. Dana 60 / 14 bolt - 40" MTR/s

Hopefully someone is running something similar and can help point me in the right direction.

I'm running 6" front springs up front. With the weight of my big block, I would say i'm around 5" of front lift. I'm having some front drive shaft binding and really don't want to do a T-case drop. I was thinking of bolting in the solid steel shims (2 on the passenger side and one on the drivers). From what I have read, seems like I don't want anything over 6* to keep it roadworthy on the street. I am torn between the 4 and 6 degree shims. I am leaning towards the 4 degree ones to be safe.

I guess my question is weather or not I should do 4 or 6 degree shims. I will also be clearancing out the drive shaft for a bit more angle here soon.

Any thoughts?

Why not the T-case drop? Pretty simple to unbolt about the OEM spacers from top to bottom and bolt back up! Gives you less angle and only takes a little clearance away. I had custom drivelines built for $200 at a local driveline shop. That's probably the best thing to do IMO.

Are you having clearance issues or binding issues? If you lower your transfercase, it actually makes the front driveshaft angle worse than it is now. It lowers the rear of the case, but raises the front, thus making the angle worse. If the CV is binding, you can grind down the stops to get a little more angle out of it.

Yes, thats why I really dont want to drop the t-case. Don't have my angle finder handy but yes, it's binding a bit at ride height with the factory shaft that has been lengthened a bit. I'll grind the stops here when it warms up but I think the pinion needs to come up a bit to help.
