I"m starting this FJ40 rebuild thing and finding my metric tool collection isn't nearly as complete as my SAE tools. To save me a trip to the tool shop mid-rebuild can any of the experts out there give me a heads-up on the larger nut sizes found on the rig. I have a double set of all the wrenches up to 19 and I have most sockets up to 27. I'd rather just buy a few individual wrenches over 19 mm that I might need and not a complete set of a bunch of wrenches that will never get used. Thanks.
