Thread size on throttle cable clip bolts?

[Harvie]

My factory cataloge calls for a 4.2 X1.2 X .8 bolts(?) and I am at a loss to what size that might be.

These bolts hold the clamps that keep the throttle cables on the top of the plenum and the cover over the end by the throttle body.

I lost one of the nuts (they are 4mm X.75) and all 3 little bolts and need to get new ones and tap out the holes.

Anyone have the correct bottom tap size? (All I have is 4mm X.70 and .75)


I will go up to 5MM if it is a real bastard size and just get 5mm torx button head bolts.
