Thank You !
As it turns out , you're a bit too late , I gave the truck away after getting it all sorted out and doing the -one- job I bought it for ~ no one wanted to give me $1,500 for a nice old truck I rebuilt and put over $3,700 in parts alone so I donated it to a rip off charity as I can no longer drive a clutch .
I'm now building a '69 C/10 shortie with TH350 tranny , it has a 250 now , I just got a '66 294 for it so I may be asking you for more parts ere long...
