390 heater elbow - can I make one?

I cannot seem to find any place that has the correct heater elbow for my 1968 390 in stock, so I am wondering, has anyone ever taken modified a 69/70 Scott Drake repo to make it correct for a 68?
I would think it would be pretty easy to do if the fitting was soldered to the tube.

I found these two at West Coast Classic Cougar.

Good luck.

Did you try Mansfield Mustang?

Yah, WCCC doesn’t have any and neither does Mansfield. I can find plenty of the 1970 version.

The one that badcatt posted a link for is D0AZ-18599-AR. The one I need is C8AZ-18599-AR, which is a little bit shorter so that my anti-backfire canister and breather can clear it. Here’s a picture I borrowed from the Mansfield site showing the differences.
