rear discs and wheel studs

after converting to rear discs I found the studs a bit short.
I found a cheap and safe solution.
Dorman part 610-260 (81-83 Merc cougar rear) 9/16 longer overall 5/16 more threaded, this stud has the starter neck "nipple".
As a lug nut upgrade I picked Dorman 611-093 this is a 1/2-20 Bulge seat open end zinc plated lugnut with a larger 13/16 hex head.
