Amazing well thought out and executed. And people think we just bolt stuff together.

Long overdue for an update…
In 5th gear the chain was hitting the head of the sissy mounting bolt, so I switched to pan head. It still didn’t clear.
So we tacked the bolt to the special mounting washer the ‘72 Barracuda needs.
And shaved it down to give a flat surface on the inside so the chain can clear.

Slick fix!!
I thought I took a picture, but apparently not. I used two spacers behind the front sprocket to get the chajn to clear the fat rear tire. But this was causing too much kink in the chain. So I had my fab shop mill me a spacer slightly thinner than the two spacers, then slightly thinner than that. I’ll test them after I get the caliper mounts situated.
You may remember where I left off with the mounts on the previous page. So…
We tacked them on and built up the weld to cover some gaps because the mounts don’t sit very well on the frame.
I ground and smoothed those down.
I think it came out well. It’s a little hard to see in the photo, but I blended them smooth into the frame so they look like they’re supposed to be there.
Next I’ll reassemble to make sure it all works like it should.

Testing the caliper mount placement with the wheel on, making sure I can get good alignment and adjustability. It’s all good. The mounts look better than I thought they would!
Set up the drive train with the thinner of the two spacers.
But the lower chain rubs the tire.
The sprocket also had a wobble that was throwing the chain, so I swapped it and put on the larger spacer. But…
Chain Is still close to the tire. When the letters are on it’ll be worse. The way I got around it with my last bike was to put a spacer behind the freewheel. But I’m not sure I have enough space in between the frame and the freewheel to move it out. I’ll have stew on it and let an answer soak in.
On a good note, this remade flat bolt gives the space the chain needs.

I thought I was the only person to wear socks with flip flops. Live and learn I guess. I do that to hide my ugly toes, it's not a fashion statement.
Can you flip the chain wheel to concave outward? That might give enough clearance.
In the winter I do when I’m in a hurry. Only in the garage.
Chain wheel doesn’t change when you flip it. It’s centered.
