I currently have an 89 cav. that I put a 3400 in. I made the front motor mount my self instead of buying one for $140.00 on line. When I made the mount I made it so I could mount the new ac compressor......Now the problem, I don't have lines that will hook up at both ends. I have the ends I need and am a little short on cash right now so I can't have them made. Has anyone ever welded there own? I have experience with welding aluminum, and already have wire in the mig welder......Can this be done? Will it hold to the pressure or not? Any help would be greatly appreciative .
