Tim,
Thanks for the help, I believe the pics you sent from Denny's truck explain everything. According to the 48 - 51 shop manual, the rear brakes for the 1/2 and 3/4 ton seem to use the same parking brake lever and I can definitely see that lever set up fitting perfectly on my truck. Yes, I have Bendix on the front and I wasn't planning on converting the rear to Bendix unless it can solve my parking brake problem at the same time and it seems to me that finding the parking brake levers you show in your picture are just as hard as finding the ones for the Huck unless you know otherwise?

I'll check the drive line forum and see if I can get help there.

Thanks again!
Larry
