What disk brake upgrade for a 74 duster, not Wilwood

and with an 8 3/4 on the back you can use aussie falcon (mid-70s-mid80s) rear disks

the caliper bracket is flat plate and can be sloted to fit without puling the axles shafts and re drilled to the pattern for the 8 3/4 back plate
and the similarities in handbrake cable lend themselves to easy conversion
let me see if i can find the article
Yep spot on, my diff guy straight away said to use the ford mid 70s disks as dirt cheap etc etc. Looks like you know your Mopar a bodies world wide haha.
