Must. II guys need some help

OK, "46 Chevy 1/2 T Panel Delivery, 350 SBC, Heidts cross member & Suspension, Flamming River manual rack. I've got a pretty good shimmie around 50/60 MPH and a little at low speed. I had 1 bad inner and 1 outer rod ends that were replaced and had the front end aligned at a good shop and watched it being done.
The final numbers are:
all numbers are degrees
Caster- L-1.4 R-1.5
Camber- L -1.1 R-1.4
Toe- 0.15 both

The wheels are Weld Wheel Pro Stars, 15" X 7"
We are thinking it might have something to do with the moveable weight thats inside the rims. And the front springs are Eaton 350lbs if it means anything.

Any ideas??

Thanks

Yep. Jack up the rear tires off the ground with the jack at the pumpkin and chock the front wheels. Get in and run the gears to 50/60 mph. Vibe not there, front tire balance. Vibe there, rear tire balance or driveshaft. Remove rear tires and run to speed. Vibe there....driveshaft. Vibe not there, rear tire balance.

Great tip! And don't forget to use jackstands! I can visualize myself doing this, and the jack giving way, and........zoom! Right into the neighbor's pool!

Thanks for the info guys but I should have also put the shimmie is in the steering wheel not the seat, the driveshaft or rear tires will put the vibration in the seat. Right?
