Steinberger

Recently bought a 1988 XL-2 with one of the bolts missing that holds the front panel on.

After seeing posts on other Steinberger forums asking the same kind of question, I asked  my engineer father-in-law to figure out what the thread was. It's an allen cap screw No 6 unc 1 1/4 long

that equates to ( 0.138 dia with 32 threads to the inch 1 1/4 inches long under the head). He got this free over a trade counter.
