i have some new in the box aluminum brake drums, they are stamped gm? cant figure out what they go to? they were made in 1996 72 fins 5 lug bolt pattern, 11 1/2" tall and 3" wide on the outside? what do they go too?????
whats the bolt pattern? there were offerd for one year only on camaros in the early 80's dont know what year...
i just googles this up, top of the list, how would one mount these on the front of a car? Now, the truly hard-core wrecking yard hunter may know that GM built aluminium rear brake drums on selected vehicles (a partial list for wrecking yard hunting would include: '80-84 Buick LeSabre, '78-81 Century, '78-87 Regal, '81-85 Riviera, '82-92 Chevy Camaro, '86-89 Impala, '78-81 Malibu, '78-88 Monte Carlo, '80-85 Olds Delta 88, '78-82 Cutlass, '80-81 and '83-85 Pontiac Bonneville, '86 Parisienne, '82-92 Firebird, '78-85 LeMans , and some other applications). For those early A-, G-, or F-body Pontiacs with 9.5-inch rear drums, these later-model aluminium drums slip right on in place of the stock, heavy iron units! Being lazy, errr, efficient, we easily found a set of these aluminium drums for $50, after a few minutes of casual hunting on eBay.
Those particular drums suck bad and were prone to warping in their original application. Pretty much anybody adding performance to those cars went to steel drums.
(5 X 4") bolt hole pattern the drum is 11 1/2 tall, 3" wide on outside, 2" inside with 72 fins? i have 4 sets new in the box the are stamped gm but have no part numbers on them they have numbers on them but gm says they are not numbers they reconize
Here's a pic of a 65-6 front GM aluminum brake drum that was available on a GTO, 5x4 3/4 bolt pattern.
