    Hello, I had a custom set of wheel made for my 88 TR. Unfortunately, my lug bolts are too short. So, is there a list or chart that shows all the shaft lengths and cross references the factory part number?

    Thanks in advance

    Eric

    Easier (and cheaper ;)) to just buy the length lugbolts that you need from Hill Engineering/Ricambi America.

    The standard TR wheels (not centerlock early wheels, not 512TR/M wheels) use a lug with 30mm head, 40mm length from the end of the bolt to the start of the conical head (and 20mm of that is threaded). The bolt size you need will obviously be dependent on whatever custom wheel you've got.

    The custom wheels for my Portofino had shallower pockets than the stock wheels,so I needed shorter bolts (32 mm versus about 50 mm stock). I got the new bolts right away from Formula Dynamics in Las Vegas.
