Chris, I am not aware of any like that. Wish some enterprising, smart type would make and offer such a thing.
In lieu of that, I just bought one of the 8BA style front covers and bolt on cam gear drive to put on a 59a in order to run a converted Chevy distributor. I found that using early water pumps, there ain't much clearance between the housing shaft back of the fan belt. So, I am messing with a non aluminum Chevy distributor to turn down the housing shaft for some clearance. Also, I am going to have the distributor sit up more for belt clearance under the housing base. This will require making a longer distributor drive shaft rod. I figured the steel distributor housing will have more meat and strength for the extension than an aluminum housing. Pictures later when I try to get all of this together.
If I cannot get adequate clearance on the shaft for the belt from turning it down, I may have to engineer a double pulley for the water pumps. My buddy Kahuna sent me one and it has given me an idea on how to make some double pulleys.
Apologies to the purists for this project.
