So, now there is a different part number, does anyone know if it is actually a new and improved bolt? Thanks. I just want to do this once and hopefully get it right.

Toyota often seems to change part numbers, and sometimes with no visible change to the part (it could be something as simple as them changing suppliers for the part and hence revving the part number). I bought some of the 90119-14151 bolts and there does not appear to be any difference in strength rating, plating, etc. with the new part number.

I personally plan on checking (and perhaps replacing) the bolts once per year.
