I am sure Jared can confirm but I understand that the part numbers tell you the diameter & length as the first two digits after the dot indicate diameter and the last three digits are the length
0090-07090 = 7mm x 90mm
0090-07110 = 7mm x 110mm
The VB250/360, H6/7 360, H7 250, VE 250/414, VF250/414, VG250/414 should all be the same as they all use the same crank cases with very slight machining alterations. Again Jared could confirm.
There are a couple of the bolts that must be the correct length or they foul an outer case or rotating components while others can be slightly longer and it does not matter. The 7mm spring washers are difficult as I have not found a convenient replacement short of ordering a large quantity. Some 1/4'' ones do fit but are tight which risks damaging the thread.
As far as the 'o' rings go just go to a bearing shop and ask them to supply them at a few cents each, I think 1/4" fit perfectly.
