[Healeys] Installing New King Pins

[Healey List]

Hi Everyone
    I am in the process of installing a new king pin on my BJ7. I Want to 
know the amount of end clearance that is required. I have measured mine with 
new king pin and bushings installed and is about 22 thou with a feeler gauge 
I believe this is to much ??? Does anyone on the list know the amount of 
clearance that there should be ??? Can I then built up the trust washer with 
shim stock to take up the end play ??
                                 Bob
