To enable use of these centre main straps, the centre main cap has to be machined flat to the nearest cut, to level the cap between the main cap bolt holes horizontal surfaces. 

To achieve maximum thrust washer location, it is possible to machine the cap down its centre section using a one inch mill cutter. However, either a good tight radius on the corner or slight chamfer off the strap edges where it mates to the cap is required. This is to ensure an unimpaired flush fit between the cap and strap. Make sure the mains cap/strap bolts do not bottom out before full torque value 65lb_is reached. Threads should be DRY.

Importation rules regarding vehicles are very specific: Only those over 25 years in age may be brought in to the USA without compilance to Federal Motor Vehicle Safety Standards (FMVSS).
