I have disassembled my ST front end for an alignment check, but I'm temporarily stuck on ignition switch removal. The fastener appears to be a Torx, but is a very loose fit on the smallest Torx that fits. Before wrecking these bolts, anyone know the correct spec.? I've looked, but can't find anything on it. --Tim Shevlin
Looking at the parts list, it is Honda P/N: 90107-MGB-000 The description says it's a one way bolt (requires 2).

Follow-up: What I found is that the bolts are really, really thief-proof. ("one-way" as noted) The heads are rounded (pan-head?) and there is no recognizable tool pattern in what looks af first like a rounded-off Allen socket, with only a half-dozen micro-dimples on the inside surface. The factory must use a special installation tool somewhat like a Torx bit--- and a lot of pressure on a bench setup. Plus, there is a widely-spaced reverse spiral cut across the threads, another anti-theft feature, I suppose. I used a #5 bolt extractor to easily remove these bolts, but I needed to grind off about 1/4" of the tip in order to get the extractor to bite in the shallow recess.
I am confident enough that switch access is way too hard for a thief to bother with (and for what, a key number?) so, I intend to use standard Allen bolts on reassembly. Tim Shevlin #1183
