...One of mine has a warp and needs replacing....not a huge panic but a this-summer to do item. Some quick searching hasn't turned up a lot of options. Are these things readily available? Is there an interchange with any front drum B-Body car or it this yet another example of some weird 68-only Buick-only part? Thansk in advance guys. Dave
They should be 90 fin aluminum drums. They will be Buick ONLY. Available used ONLY for aluminum. They do make new cast iron replacements. Kinda pricey. Used drums can use '66-'70 ALL full size Buicks & Rivs. MAX OD 12.090" BEFORE resurfacing.
