Tubular upper arms-I feel lucky tonight

70Hardtop said

I have some that i havn't installed yet. Don't know the brand as i bought them new from another guy who ordered the wrong ones. They have the same silver R/L sticker in the same place, but the pivots are thinner. So now i'm a bit worried. Is there any way of telling if they have been MIG or TIG welded?

BTW, 72bluNblu, nice info on the UCA story, thanks

CAP also sells their arms with heim joints, so that might account for the pivot difference. I'd try to find out where he got them.

As far as MIG vs TIG welded, it depends on the weld. On average I'd say TIG welds are smaller, cleaner, more uniform welds. But a good MIG weld can look much better than a bad TIG weld.

Post up some pictures of the arms, we can probably figure out which one's you have.
