Reproduction shifter boots for 4-5-6 Chevy K10/K20

[LILRED66]

I am in the process of doing a frame-off on my friend Lee's '66 Chevy K10 lwb fleetside truck. We are dressing out the interior and looking for a source for good, quality reproduction shifter boots for the SM420 floor shifter and 4x4 shifter.

I have a few stock 4-5-6 Chevy K10/K20 trucks with the factory shifter boots and have been unable to locate a good quality factory reproduction. Any suggestions would be appreciated. Thanks for your time and suggestions.
