wilwood coversions..what next??

The Wilwood kit will probably work okay for your car, especially since it is a lightweight car and you aren't going to drive it a bunch. If you have the 10.75 x 0.81 rotor kit then just remember that you have a marginal brake system and drive accordingly. That is smaller than anything the factory put on there.

For the master cylinder the easiest thing to do is just buy a modern aluminum MC with the plastic reservior. Those are lightweight and fairly inexpensive. Lots of places sell them but before you buy one you'll want to take a look at your Wilwood kit to see what size the caliper pistons are. The smaller the pistons then the smaller the bore size you'll want on the MC.

If the front pistons are really dinky then you'll also need to change the size of the pistons in your rear brakes or else the balance will be off. This is the biggest problem I see with people doing brake swaps. A lot of guys just buy random kits and try to bolt them on without knowing anything about the proper ratio of front to back piston area or matching the piston area to the MC size.
