Aloha,
Depending on the Date your car was born, the front tow hook could be the larger 22mm size. The only place I've found a bolt that big was at the Komatsu Heavy Equipment Dealer. It's too short to use like the How-to. On day I'll do it and document the install. I believe there is a kit ($$) out there for both size fronts, just can't remember where I saw it though.
