Update. As far as the arms go, I went and looked at the M37 arms, the original 3B frame, and this frame are identical. Same part number stamped and everything. So Dodge M-series shared some little items with Jeep. Learn something every day. Got the glass back. (1 month). But the guy is into old stuff, and charged me 1 hour of labor plus material. Cutting the safety glass around a radius involves denatured alcohol and flame at some point, so I was impressed that I actually found someone with old-school skills. And he was happy to do it. And actually reassembled all the parts correctly. Looks good to me, I like the light tint. I started looking at the next task-installing the outer rubber. The one sold to me is, let's say, questionable, with what I now know. After messing with it for half an hour, boiling it in a pot, etc. , I realized it's not going in, without a fight, or maybe ever. The profile is wrong. I emailed the seller, who admitted it's a bitch to get in, but I can see, even if I cram it in 1/4" at a time, it's not right, and won't stay in the frame. I pried the 1953 original out to see the profile, and it's completely different. why didn't I catch this before? ****, I don't know. I'm busy. So, next morning I call Pete to see if he still has NOS weatherstrips for a 3B. He answers..(and use your best NY tone)..."DEBELLA!" He wanted to ship it to my dad, who is deceased for 15 years. I set him straight, but we had a short talk about my dad. It's on the way. I love New Yorkers. So next, I am ready to paint the outer frame, but it has been way too cold. I ordered and received Summit's hot rod black urethane. Cheap, fast, and we'll see how it goes once I get anything resembling painting weather.
