Grim: Find an old H-fact 005 case-set, they make for a passable 6502 case. You want that slightly curvy lug as seen in the pic below.
Noob 111J on top, H-fact 005 on the bottom. You want the lug profile of the bottom 005 case-set for a 6502.
If you polish the corners of the lugs around the lughole with a dremel and some polish, you'll get even closer to the softer edges of the 6502.
Even better, get a Kuvarsit v1 DLC case (which is actually PVD'd)
(BTW - I learned this from reading W0lf's posts - Thank you sir )
