Hi all.
Does anyone have a technical drawing of the bolt pattern that mates the gearbox bell housing to the 4.2 engine block?
I’m hoping someone can save me a few hours of work as I’ll have to split my setup to take the measurements.
Thank you in advance.

Hi Steve,
I would be most grateful if you could do that for me.
I’m not sure if you could place the housing on a scanner or photocopier? If it’s copied in sections I could then stitch the images together, in an ‘actual size’ resolution, and work from the template to build a model in CAD.
Once I have a technical drawing and assured the measurements I’ll post it here for future members.

I will be very interested to get copy of your final drawing. Would be much appreciated thank you.
After that, I would need a drawing of the gearbox to bell housing face, location of the primary shaft and length of the bell housing.
