Thanks all.

According to the dimensions given on Speedway’s listing for this item, the overall length is 21 5/8”. According to the frame drawing in the 48-51 Truck Shop Manual the outside width of the frame at the front is 25 1/2”, for 3100 and 3600 trucks. It is a little wider where the mount would go. That’s why I thought it might work.
