Hello. I had been looking for an 80 for quite some time and out of the blue last Friday, my wife surprised me by saying she had found one and bought it (sight unseen). It showed up and has a cracked frame. The more I look it over, it looks like it has been used in some tractor pulls. Anyway, I did some checking to see if anyone had any posts about welding up the frame rails on a 50, 60, 70, 80 etc and found nothing. Don't know how rare this is. Wanted to know if anyone knows if the frames were made from [u:65e08d9a55]cast iron[/u:65e08d9a55] or [u:65e08d9a55]cast steel[/u:65e08d9a55]? There are a few welds on here that look like they're with 6010 and not Nickel-Cast and they're still not cracked. The frame cracked out again, but the others on the front end and radius rods didn't. Normally, 6010 won't last 5 minutes using it on cast iron, but it might on cast steel if it was pre-heated. I am going to try and get this frame fixed but wanted to know what steel it was first. If I can get it fixed, great, if I can't, it might become a yard ornament. I enclosed some pictures. Thanks.
