My Gt750 has ugly allenhead screws on all the covers. I bought a set of repro phillips head screws and want to change them over. When replacing do they have a) a spring washer, b) a flat washer or c) no washer with them? Ta

No washer, and I use a T handled screw driver to snug them up. 8)

If at first you don't succeed, just get a bigger hammer !

Thanks Ian. Yeah, I think one of those T-handled ones might be a useful addition to the tool box. Too easy to ruin the heads with a basic phillips head I've found :x
