I have converted my hydraulic cooliing system to electric (thanks to lsmonk for all of the help!) and am now dealing with some pump noise. I tried to search regarding how much shorter belt I needed to bypass the pump altogether. Does anyone have a part number or length off of a belt they used for this? By the way, the fan cooled great today in mid 90 degree weather with the ac on.

Just do the old string trick. Run it around the pullies like the belt would go (including the tensioner(s)) and get a belt that size and a size bigger and smaller. Run whichever one fits and return the others. I did this many times with my 87 after running underdrives, then when I put a blower on it.
