Tapered drop blocks? Recommendations needed

[Dattebayo]

My old 850 has straight 3" drop blocks on the rear, and the driveline is complaing a lot. I don't really want to take these off and have the truck be out of service while I wait for these to be machined, so I'm thinking of buying a set of tapered 4-6 degrees from the factory (based on my truck's measurements). Does anyone know of a good, reliable source for this? I can't find anything online.

Thanks!

I was just reading reviews of drop blocks on Amazon, and this company has affordable angled blocks w/ good reviews:

How did you determine what angle you need?

I got their 3-degree blocks in the mail today (for less than $40!!), but I'll take some photos of the fitment since I've heard that more D21s need 5 degrees or more to work...
As for how I got the measurement, I used some serious redneck ingenuity involving string and a school protractor.

Looks good so far...






Little bit of finger in that last one, lol.

Anyways, I now have a sunburn and it took too damn long to get that done. Almost 6 hours with clean-up and equipment lifting to the street and back into the house. My freakin jack weighs at least 100 pounds, ugh.
