Can a front drum brake set-up from a E Body work? A customer wants to up-grade to Large Bolt Pattern on his A Body to accommodate his rim choice, but we were both wondering if he can retain the drum brakes all around... I know it would be way better with front disc brakes but that's not the answer I'm looking for...Thank you... *CHECK OUT MY NEW WEB SITE !*

I think labor was like $75, shipping more obviously, and had them back in a week. I'm sure Moser and all the other ones can do it too. Worked well and have had 0 problems in 6-7 years drag racing it. 68' Barracuda (4 speed) 64' Savoy (4 speed) 65' Satellite (girl tranny)

You can use any '72-earlier B drum assembly or any E body drum brake/spindle assembly as long as you use '73-up A-body upper control arms since they have the big ball joints that you will need.

Did '73 up SBP front drum A bodies use large or small upper ball joints? Large ball joints in the upper control arms for 73-76 wether it's drum or disc brake. Just took off a pair of A arms from a drum brake 76 Dart in a wrecking yard this morning, as a matter of fact. RF-4C Phantom 69-370 Zweibrucken, Germany

I'll eventually need to do the same. Ron In sixty-five I was seventeen and running up one-o-one I don't know where I'm running now, I'm just running on Jackson Browne-Running On Empty

I had a 76 Dart with 9 inch drums and a slant sick. I tried to use my 10 inch drum assembly from my 70 Charger but the ball joint stud was the small size. I've wondered about that for years. Who knows, really. As old as these cars are, they have often had several owners and several parts swapped around.

I have been told that there are some drum/hub assemlies from some AMC vehicles with 4 1/2 inch pattern drums, that will go directly on the A body mopar spindle. It was a pacer, or Gremlin I think. Maybe someone else here knows, or you may investigate. ------------------------ It doesn't matter what you do.........As long as you look good doing it !
