Help ID a833

Honestly there is nothing wrong with the OD boxes, even the long tail truck and van variants, they are the same length as a 727 and fit an a body just fine with a shifter adapter plate. Dont get caught up in the weak aluminum box overdrive ratios bs. They are plenty strong, offer a nice low first for snappy launches and a slight overdrive in fourth which is awesome on the highway. The steel shifter mount plate in the picture looks like what the factory used in trucks and vans.
