alright the metal line from the radiator to the fire wall on the passenger side is shot can it be replace with a high temp rubber line? if so what size is that line if any of you have already done so.
second i turned the key for the first time and absolutly nothing happend the only electical thing working is the head lights not the lift motors no markers no interior lights no dash lights. Im hopping for blown or pulled fuses, is this the most likely cause our an i looking at a major problem?

probably a fuse. check all fuses and the fusible links. on the heater line, well, i would not personally use this rubber type line. i would go to the junkyard or try to find one for sale or at an extreme, get some jb weld and repair yourself. there is a reason why it is steel and not rubber..

well i figured on eventualy replacing it with a new or used metal line but the ends of the metal line are conected to the radiator and heater core with rubber hose thats why i figured on using a rubber line as for jb weld its beyond that
and another thin the radiator has to small lines comming od of the driver side at the bottom they are capped at the moment what whould these lines have been used for? trani cooler possibly

yes, since the radiators are interchangeable with manual and auto trannys, those lines would be where the automatic transmission lines hook up. unless a vehicle with an automatic trans has an actual trans cooler, they use the radiator to help cooling. the trans fluid doesn't actually get into the antifreeze as there is a seperate channel for it to run through.
