Building up a 70's Super Paort (Schwinnliness). And Orderd a hanger from Smart Bike Parts. Didn't Receive... out of stock. Reordered... This time they Sent a SCHIM Turney MtB derailleur. I Q: why, they say, "It's got the right Hanger" (i.e. old School like GT 100) I disassemble the thing only to dicover that instead of a threaded hole, there is a Pressfit/rivet-like Set pin ( thought it was screwed in until I tried unscrewing it.... once I beat the **** out of it it just spun..... poop!) So I'm back to square one. I'm gonna try the NOT SO Local Bike shop, But I wonder if they'll have anything this old laying around.
I looked at a Walmart huffy in the ditch and it Too has the set POST not a screw on derailleur.
Can this be drilled and tapped? Any idea what bore and tap threading???
