2wd 1977 Blazer LS swap, mild drop….escalating

[Advanced Design]

When I went on pause, I was replacing the KWIK ac mounting bracket, shown a few posts ago, with the Holley mounting bracket. The Holley look fits in better with the look of the factory accessory drive on the other side of the engine.

There was an issue with the GM tensioner not fitting as it is too thick / deep between the mounting bosses. The tensioner contacts the mounting bracket at this location before seating and tightening down. A tensioner from another source worked fine.

And the Holley instructions had the ac compressor mislabeled as an SD5 rather than an SD7 as shown on the label on the compressor. Anyway, using the Holley mounting hardware Holley had labeled as SD5 worked for mounting the SD7 compressor.

While I didn’t like the look of the KWIK bracket, I’m not sure it was worth the work and expense to switch over to the Holley bracket.

Having the new shop stool, which is an early birthday present from wife and our two daughters, helped increase the comfort working on the brackets.
