Make sure the center "big hole" is the correct size. The brake drum
"centering" is the most important aspect of this job. If you need to open
that hole up, bring the drum and a hub to the machinist to get it right.
Think "hub centric".

Well, you might be able to get by without opening up the stud holes, your
TR6 comes with pretty wimpy 7/16th inch lugs... on my 260Z brake drums, the
holes just needed a little "chamfering" on the back side... of course then
I installed 1/2 studs so then I had to open the stud holes up a lot.
As for the retaining screws - you don't really need them, but if you insist
- go for it.

They look nice if you bead blast them... but before you do anything make
sure the ID of the brake surface does not exceed 9.055 inches, at least
that's what's cast on my drums. You might also want to "crack test" them.
Of course turning/crack testing should be done first.

No paint. These babies get HOT.
