I've recently been informed of a gas cap clocking issue with the '65-66 Scott Drake Zinc Plated neck. The issue being the gas cap will not turn far enough for the artwork to be level.
Interestingly, I was also informed that the Painted version of this neck (made by a different mfr.) available from various suppliers does not have this issue. I had originally bought 1 of these painted necks from Summit as it was a cheaper than the Zinc Plated one. Not liking the looks of the blistered paint around the stake marks (even after touching up), I felt the added cost of the Zinc Plated one was worth it so it was "1 & done" for the painted version.
After discovering the issue, I started stocking the painted version again and even found a supplier selling the Goodmark version for less than Summit. Well this vendor must have had them on "clearance", as they no longer list it.
Having 4 of the Scott Drake Zinc Plated ones in my inventory, I figured I needed to do something so I bought a Scott Drake 1965 Mustang gas cap to confirm that there was no clocking issue if the proper gas cap was used ... WRONG ... even the Scott Drake cap on the Scott Drake neck has the problem !!
So, I put a cut-off wheel on my Dremel and cut back the stops and eliminated the CLOCKING ISSUE. Took maybe 10 minutes.
All my '65-66 Scott Drake necks are now fixed and this mod will be done to all of them from here on out.
