Found Any Iver Johnson straight rear down tubes out there?

Any Iver Johnson straight rear down tubes out there? Or suggestions on tubing. I'm looking online at 5/8" OD tubing. I just got back from Lowes with 1/2" OD steel tubes and they are round and of course not chunky like 5/8". Maybe if I flatten the 1/2" tubes I can get 5/8" My both rear down tubes are sketchy. As you know the rear down tubes are not round tubes. I knew the frame need love before I bought the frame. It's going to be a static display bike. THX

Those tubes look swaged, donor bike fosho. Either way, Moly tubing over low carbon steel

Upon second look those might be the same diameter all the way down. Just look for 4130 cromoly tubing from a local metal supplier. Is the frame brazed, or welded?

THX for trying to help. Trying to save this old boy. I'll check the product you suggested. I'll look after supper tonight for welding or brazing. Stay tuned to this channel/dilemma.

Both rear down tubes are flat on outside and inside. Same size from top to bottom.

Then they will have to be flattened

Most likely 1/2 tubing

You might be able to ovalize the tubing with a rolling mill. And those tubes are called "seat stays".

For a a static display bike, would a patch repair with JB-Weld be appropriate?

Why not put a “wanted” ad out for a damaged frame to remove the rear stays as replacements? I have/had a girl’s Iver I couldn’t give away at the last MLC swap. It either went to the scrap guy or is at my place in Hershey. It was mortally damaged at the head tube area but the rear was perfect. If I still have it you are welcome to it.
