1980 K30 3" lift block question

[75Monza]

Hi guys,
I'm looking for good quality 3" iron tapered lift blocks for my '80 K30, preferably in a kit with the U-bolts. Anyone know of a kit part number and where to buy? Been searching around, can't seem to find what I'm after...will block for K20 work or is it different pin? Getting ready to set up drive train, have 3" tough country springs going in the front and the 10 spring w/overload in the back.
Thanks

I used a Fabtech 3" block #FTSBK3. In front I have Tuff Country 3" HD springs. Due to the fact I have the upper factory over loads, my spring shop made custom square U-bolts for me. I believe the blocks have a 4 degree taper. Blocks are the same for all Square bodies. Just make sure you don't use aluminum.

My truck is running 305/70R16's. With the re-arched rear springs and new fronts, my lift is actually about 3.5".
