Dan I removed the rails with a cold chiesel on the rivets and used a cutting wheel to cut the rail at the door post and also at the rear crossmember.Worked pretty well. I removed one side at a time. Removed rail and installed new rail.It helped me keep track of the line up of everything! My original rails were completely rotted but believe me even the old rusty rotted rails were enough to answer some of the question as to line up and positioning. I welded my rails in!I used a mig welder. With my Subrails in such poor condition as is yours, you can see how much support they provide to the strength of the body. I felt that welding them in would be the best choice. but you decide! Dan, It's not a hard job! Everything on the car is riveted together in some form. So move around the rails from back to front popping the outside panel rivets loose and remove the crossmember rivets. Then measure the length of the new subrail against the old. and mark for your cut.Just be careful not to cut the original good side too short!Then but rail ends together and weld top and bottom. Then weld on crossmembers. Contact me as much as you need, I'll help where I can! Dean |
