Stock height, lowered?  If lowered howin the rear?  Who's trans mount for the 4L80E?
If the trans angles down 6, and the Yoke is 2 degrees up, what is the Driveshaft angle?

I'm measuring the angles on the flat part of the yoke.

thx for the reply. I've read and watched the spicer stuff which is what I'm following, at the moment my rear end (10 bolt gmc w/373 gears) is up at 2 degrees while my transmission is down at 6 degrees and the trans is hitting the tunnel. am I doing something wrong here? thx again

What is the angle at the Trans?  What is the angle operating angle of the driveshaft?  What is the angle of the pinion?
How are you measuring the angles and where?

OME as stated by bd is popular in offroad and is Australian based and owned by ARB.
I have never used them on any 73-87 truck, so I cannot comment on that.  I have used Fox and Rancho for 4x4 vehicles, Fox being what I used on my Jeep LJ.
Which Bilsteins do you have and what issues are you experiencing?  I have used these in the past and didn't have issues so curious.

Thanks bd, seems like it.

The impression I get from their write up is that they feel they're good for both Street and O.R.. I don't off road so would hate to find out the hard way.

BTW, I know there are Bruce Willis fans of Bilstein. I have them on Cherry Bomb (wife named her  ) an I'm not impressed, so looking elsewhere.

81 short bed, 5.3LS, 4L80e. I'm having trouble getting my pinion angle correct as my 4L80 is up as high as it will go and the angle is still out by 3-4 degrees. I'm currently using ICT Billet motor mounts and wondered if anyone has a suggestion for lower profile motor mounts?  Thx

As long as power reaches the headlamp switch, it distributes that power to the various running lamps (except for the brake/turn lamps, which are powered through the turn signal switch).  The headlamp switch has two power inputs: one strictly for the headlamps via a fusible link, the other for all the running, dash, and cabin interior lamps via the fusebox.  The issue is probably inside the cab if you don't have power through the firewall bulkhead connector.  Verify power to the headlamp switch, then check power on each switch terminal.  If the switch operates properly, move to the wiring between the switch and the bulkhead connector.  Follow the links I provided; all of the information is there.
