Engine mount, drill or tap?!

[smalltime_hillbilly]

Hey!

so i'm just about to fit my engine into my bus. Its a recycled D code case.. Basically, I got an adaptor plate to fit it into my bus, but looking at it now it already has 2 holes drilled and tapped and not the bottom one?! my first question is...

Can I drill and tap the bottom hole to fix my moustache bar correctly? To me it looks like its just a solid lump so should be able to?

Note the top 2 holes are M8.. Ive read there suppose to be M10 and the bottom hole M8. Would I open up the top ones to M10, or would M8 suffice?

Has anyone tried it with this case? Dont want to **** it, but also the adaptor looks dodge as hell.


2nd question.. does anyone have the dimensions of the moustache bar ( I forgot the name) studs? mine only has the bottom one fixed!

pics of what I have, help me! :shock:

Yes you can drill & tap those bosses on the case

specs as per rat well is
top 2 holes M10x1.5 28mm deep
Bottom holes M8x1.25 28mm deep

anyone know if this sounds about right? bit squeaky bum time drilling 28mm into the bottom stud

sorted it.. used the rat well ones which worked really well.

I would drill, tap and use helicoils as this is how the cases comes from factory. Screwing into magnesium will strip the threads very quickly.
