Hi! Long time reader, first time poster. I'm about to start a new build and have a question about the compatibility of H151f gearboxes from 80 and 100 series Landcruisers. Are there any variations between the input shafts and transmission case-to-bellhousing bolt patterns from different model years that would prevent interchanging 80 and 100 series gearboxes? Are they all the same 14-spline, 32mm input shaft? I've searched the forums and can't seem to find this specific info. Thanks!
