AC brackets

Vintage air wanted around $500 for the bracket for a SB mopar. I printed the photograph out and with the use of a few measuring tools, I was able to easily replicate the bracket. Over the years I have made my own where there was not one to copy. Here are some of the tricks I have learned:
-Use all-thread rod in threaded holes you plan to use to mount the bracket. I will install these rods which then "projects" the location of the bolt holes out into space where you can simply push cardboard over them to make a pattern. In reality, I usually will take precise measurements with a caliper and lay it out but for a rough pattern the cardboard trick isn't too bad.
-I'm usually able to find at least 2 holes that are on the same plane (even if I don't plan to use one of them for the bracket), and this is how I establish a parallel plane to the drive pulley for the compressor, alternator, whatever..
-Once the component is bolted up to the bracket, spacers must be fabricated to hold the component in the proper location. Determine this with either a straight edge or a line laser on a tripod. Heavy wall conduit works great for spacers and can be cut with a tubing cutter if you take your time and don't rush the cutter.
-https://www.cvfracing.com has a huge selection of Mopar pulleys. They will not send or publish their dimensions, but I called them with the dimensions of my original drive pulley and told them I needed one like that PLUS an additional groove outside of it and they were happy to tell me the part number. Very reasonable price for what I purchased but then I didn't do the full dress kit.
-For a tensioner, you can purchase turnbuckles and pivot the compressor or use idler pulley assemblies. I couldn't find the one I recently bought to link it but summit has tons of them. I only spent around $40 for mine however I had to have the base machined parallel to the pulley as mine had a wobble as you swept it to tension the belt.
-For belts, a trick I do is wrap masking tape around the outside of the pulleys and mark where the tape starts and ends. I remove it and straighten it out and measure the circumference of it in the smallest and largest position. Then go online and research belt codes and create your own based on the length and width of the belt. There are several companies that sell good quality belts at VERY reasonable prices. It is extremely satisfying to punch in your part number and have it actually come up as a real product. I'll be honest, I screwed up last time but my 2 online goodyear belts were cheaper than one off-brand belt from my local parts store.
