F225 Yamaha- Lower unit bolts (from 30 to 25)

[frustratedboater]

I have an 04' LF225TURC 225hp outboard. I am mounting my 30" outboard on a Grady White fisherman and it needs a shorter (25") unit length. I'm planning to change the mounting bolts and trim the water tube on the motor. I've searched many online parts breakdowns and have not seen any part numbers, or seen options to buy the bolts even on e bay, or shown on the mid-section options. I realize these bolts usually stay with motor but I'm sure this is a fairly common conversion.
Can anyone help with part numbers, or any online sources? Always appreciated..

It is all laid out for you in the applicable Yamaha parts catalog. For example
