Yes, the Hawken Shop/Dayton Traister has the Griffith parts. I bought a Griffith lock from Track some years back & it was a mishmash of parts that would not stay cocked. Dayton Traister fixed it for me, but the mainspring was still weak. I swapped in an L & R or Davis which made it work well. That being said, I agree with being careful with D/T. They helped, but I had to get their attention.
