Broken spark plug wire clips from late SY and SZ cars are a real bummer; The original plastic injection molding lends itself to problems with engine temps and they just break constantly. We think that we have found the ultimate solution in reproducing these from canvas phenolic. The fit is awesome and they should last for many years to come!

Crusty SC/S master cylinders. These are impressive, but there have been instances there is almost nothing left ðŸ˜ģ as the aluminum casting simply erodes away. Brake fluid will eventually start to weep through the casting--when this happens we believe in simply replacing them--not rebuilding them.

**Originality Alert** Probably one of the best preserved SY battery boxes that we have stumbled across. Note the rope that has survived in the bottom--that is what stops the heavy battery from breaking the plastic! Correct size and configuration 27-series battery for reference. 🙂

This is the gravity light switch for all SC/S cars. It is filled with Mercury ðŸ’Ŧ It is often refit by shops backwards, so instead of coming on when the trunk is raised is goes off, but will instead stay on when the trunk is closed and drain your battery ðŸĪŠ. This has been your proper motor car public service announcement. 💂‍♀ïļðŸ› ðŸ”Đ🚘

S1 sump removed due to leaks and clean out. When removed we found the old gasket was recycled and simply siliconed back in place 😌ðŸ˜ģ No matter, we ordered a new gasket! Cleaned the sump pan, treated the casting to some additional sealant and refit it better than new! 😊

Exhaust manifold heat shields were fit to late SCII and SCIII models on the A-bank of cylinders to keep heat away from the brake fluid reservoirs and heater hoses. These are a really nice upgrade for the earlier cars so we are making some extra sets, pictured is our prototype.
