RV8 bellhousing bolt sheared

Post by rob b »

OK was removing the transmission in the Hilux to swap the manual Toyota gearbox to a TH350 Chevy automatic and one of the bellhousing bolts sheared off, it was one of the top 2, the others were very tight and I want to run a tap into them to clean out all the crud and corrosion. Does anyone know what the thread size/pitch is? I have tried searching for the answer but cannot find one.
