Reminds me, Cajun, I am also looking for the same parts for my old Clark 5 speed crash box. I will ask about those parts as well.
For reader interest, my 48 GMC has a Clark 5 speed, will have a Brownie 3 speed and has a 2 speed rear axle. Probably take me a year to hit all the possible gears, if I can remember all those gears. I bought the Brownie primarily for the overdrive. Those of you with Big Bolt trucks understand why.
Lately, I have taken to bragging, "I will be able to get my truck up to 60 miles per hour, real hot rod!"
I figure she will do zero to 60 in about an hour.
