[Healeys] Lay Gear End Float

[Harold Manifold]

Hank,

The gear box is a BN4 Sideshift for a Healey 100-6. I have a Healey BT7
with a November 1960 build date but when I took the car apart I discovered
the BN4 gearbox. Your article is perfect and confirms my suspicion the end
float should be 0.001" to 0.003".

Thanks... Harold
