I have a '72 8.5 rear in my '66 special. Still using old springs in there. Wanted to do the Hotchkis upgrade, just wasn't exactly sure which ones to get since I have a hybrid setup. Saw both of these: http://store.summitracing.com/partdetail.asp?autofilter=1&part=HSS-1900R http://store.summitracing.com/partdetail.asp?autofilter=1&part=HSS-1901R My IQ is low when it comes to this stuff. Which one would work for my application? It looks like the only difference is single vs. double pigtail. Thanks! :TU:
