Was looking at my engine hanger bolts today, and I think the lower long bolt has been replaced with an incorrect size by the P.O. What I have is a bolt that is 380 mm long including the bolt head, 366 mm long without the head, and 12 mm wide. It seems far too long, and had a massive spacer on it previously that I can't see in the diagrams from CMSNL. It also seems sloppy in the mounting holes, like it should be a thicker bolt. Can anyone tell me what the actual dimensions should be for a 1977 F2?

The grinding paste was a free sample, you should of kept it.
Glad you got the package on time. I looked at the width of the foot pegs, still seems long, and cant figure what the spacer is for. I know theres a small 10mm spacer on the inside, but this is about 50mm wide! Is 12mm the correct diameter?

Is 12mm the correct diameter?You should have two long hanger bolts. 1 for the top that has a spacer that is a strange shape with two flanges. The bottom bolt also has a spacer. The spacers are 4 and 5 http://www.cmsnl.com/honda-cb550f2-super-sport-550-four-1977-england_model17121/partslist/F26.html#results

As I'm scrapping the foot pegs, I know I'll need a different length, but want to get the right thickness. 12mm just feels sloppy.

The mounts on the rear of your engine at the back should be two different sizes, the top one being a smaller diameter than the bottom ?

Not exactly round anymore...

Looks like someone did not have his bolts tight or drilled it because he/she could not get it lined up right.
Is it on both sides ? As in is the opposite mount the same

Or they can be wielded and re-drilled.
