Great work. Did you know Isuzu built at least five VX's with manual shift and TOD??? Yes, that's right, rally competition models. You can verify this plus learn a thing or two by consulting the VX parts book. Sections 2-20 and beyond detail the pedals etc. If you don't have access let me know, I'll have my wife scan and post the manual transmission pages. Good luck.
I was not aware that Isuzu made 5 manual VXs. Learn something new every day. If you could scan the documentation I would love to read it!
