Motor Mount Lengths?

[alfredo]

I have been looking at this: http://www.boats.net/parts/search/Yamaha/Motorcycle/1978/XS650SE/FRAME/parts.html

and can't figure out what the lengths of the motor mount bolts are. Usually I can tell the lengths by the part numbers, but this isn't making sense to me.

Anyone know what the motor mount bolt lengths are?

In the link above I need to know what size #15, #17, #21, #22 and #24 are.

I think the 3 in the center are not motor related.. or might be.. the headstock one is on the frame atm so maybeeeeee.... I might go get it.. top 3 are front engine or course, bottom one is under the motor connecting the frame, 3 the same are back engine mount. And yes... I chromed all of it..
