Al,
We're just starting a loaded GS P47 this summer for Rich Firestine here in NJ, now would be a great time to get yours going too. Doubles are easier on the brain, especially with the scale stuff.Crated shipping is included in our price, check your email for details.
I may be able to help you out with the p51 too, but I'm a bit leery of taking over another builder's project...too often you end up with none of the credit and all of the blame if he's made a mess!
