Quick question...other than the obvious.....are there any significant differences between the short and long pigtail fuse boxes... are all the connectors and fuse positions the same? My early 71 should have a long one but it has a short version??? Perhaps the whole harness is a later version.... I want to buy one of the new motorsport boxes and would prefer a longer one as I expect it will clean up the wires in the dash and make a neater radio install. Thanx
