1954 packard pacific / GM 700-R4 transmission lens / radiator cap / pin hole leak

Hi Howard,
You are correct. The shift lens is for a GM trans. The 54 has a GM 700-R4 trans. The lens is from ididitinc.com I tried to match the shift pattern as best I could and just stuck the lens in front of the actual Ultramatic lens. With the old lens and new trans, shifting was quite hairy if you didn't know the car. The lens might actually fit in the original Ultramatic space with some work. I haven't tried yet though. I have another lens that shows 3 speeds and an overdrive with a housing.
Quick question, the car drives great and the temp is stable. The rad cap is a 7psi NAPA 703-1411. Unfortunately after driving this weekend the upper flange below the cap developed a pin hole leak in the neck seam. The car has a GANO filter so it cannot not take any internal radiator sealant. Do you know of any type of radiator sealant that can be applied externally to the neck seam?
