Truss rod wrench for 88 USA Jackson and neck pocket question

[Mechayoshi]

Hey everyone. I have a question regarding a 1988 Jackson Dinky Style I picked up. It’s one of those blue Crackle Dinkies with Grovers’ signature on the headstock. Mine is #190. Fun fact: Grover and I share the home town of Chattanooga Tennessee!) Anyway what is the size wrench for the truss rod? The 7mm (I think) one for my MIJ Jacksons doesn’t fit the narrow space. I’d share a pic but it needs some cosmetic TLC. (It is on the Google drive collection link on my Charvel/Jackson page if you really wanna see how it looks now.



Second question: The neck pocket has “3-10-88 Hamila” in it. Was that a builder? Not that important but kinda curious.

5/16th 0r three sixteen's, they vary with just a year difference sometimes in build. TJ had two RR that took different size wrench's I have three different allen wrenchs for my USA's. Name could be the builder or painter, never seen the name before so it's probably the painter/ company the did the crackle

Thanks. I found a wench in the drawer that worked. The size wasn't labeled though. I'll show pics when its all fixed up!
