I'm not near my work computer so I'm not sure on pricing or application, just know that is a common part number we stock. We do commonly use the FJ80 disc/drum master as an upgrade for older Cruisers. Buzz us at the shop if we can help. 801-563-1277 or info@cruiseroutfitters.com
It's not an application we've done much with recently. Physically they can fit, but they are not designed for stock springs and fhe stock spring clamps will need some modification.
