What size disks?
If you are after 7.5" cooper S disks then it is hard to find then and they will cost you quite a bit advantage is they fit under 10" wheels. Your looking upwards of $1000 for a good set unless you are lucky
Fitting S discs is easy once you have all the parts.
if you want 8.4" disks which suit 12" and bigger wheels then these are a bit cheaper and easier to find it is also possible to mod camira, honda, or some other disks to fit under 12" rims.
8.4" disk I am not sure how much they cost but I am guessing in the order of $600 - $800 they other types of disks need to be modded and unless you have access to lathes and milling machines and know how t use them I dare say that is best left to professionals.
I magine once these discs have been modded they are easy enough to fit.
with all of the discs they will need higher brake pressures to work this means that your rear drum brakes will tend to lockup before the fronts come into action. To solve this you can either fiddle about with the brake bias valve on the rear subframe or the better way is to get cooper s rear wheel cylinders and install these in your rear drum brakes.
Fitting of brake boosters is optional
