Wanted Info On Webasto replacement screws?
After bench testing a used Thermo top I bought last year and never installed, I discovered that screws on the inner chamber that holds the igniter/glowplug section to the main housing weren't
there! Damn. They are the same torx heads that are on the outer area, 4mm or so. Anybody know the exact specs so I don't have to tap these and can order from Macmasters etc?
I have checked all the parts lists catalogues and can't find the screw size listed. Been to hardware and HD etc. the threads are definitely special.
