Rear differential cover #73232 02/14/2007 3:00 PM

The rear end was a 55T...3.90 rear end from a 1957 Chev. PU... The problem is the rear differential cover plate will not go over the new gears... Does anyone know if there is a different cover that will work for this...

I'd give Patrick a call 1st thing today, if you're sure that rear is a 57, and you ordered a gearset for 57 ..... well, actually even if you're not sure Bill Moved over to the Passing Lane "When we tug a single thing in nature, we find it attached to the rest of the world" ~ John Muir "When we tug a single thing on an old truck, we find it falls off" ~ me Some TF series details & TF heater pics

My mechanic had a welder friend work on the cover and he extended it about 1 inch to the rear.. works great.. The 3.38 replacement really makes a difference in the rpms in all speed ranges...got to help gas mileage and wear on the engine.
