Rover bellhousing bolt pattern needed

[tellicorick]

Hello from Southeastern US. I've been searching, posting and looking for the bellhousing bolt pattern for the back side of the Land Rover 4.0 liter engine; which I'm told is identical to the Buick, since LR bought this engine from GM and has been using them since the late 60s.  What I need is some type of drawing file (either pdf or dxf) showing the locating pins and bolt hole dimensions referenced off the crankshaft centerline and the diameter of the holes.

I'm doing an engine swap; Gen IV series small block Chevrolet into my Land Rover Discovery and need these dimensions so I can build the adapter to mate the engine with the ZF auto transmission.  If anyone knows where I can find this file or has access to this file, please e-mail me at:   rgizbone@knology.net

Thanks,
