i just got a auto meter 5 in ultra lite speedo and i am about to put it in with my other guages fuel level 3 stooges with vacum guages. anyway my speedo has never worked and we found out why. the cable is to short. so my question is where can i find one, my trans is a turbo 350. also how hard is it to wire all of my guages and lights and stuff up? thanks

Hook the gages up the way Elree shows in this diagram. As far as the speedometer cable goes, one from a truck would be longer. I think AutoMeter has a screw on fitting on the back of the gage. On the trans side the cable will fit either a powerglide or the THM 350.
Don't have a part number for the cable but I assume one from a mid-60's truck would be longer. Best I can suggest is search around the net for a source for truck speedometer cables. They are still being made.
