82 GL1100A front engine hanger bolt size?

[skiri251]

What is the bolt diameter?
I thought it was 12mm but what I got from eBay seller is 10mm.
Parts diagram shows three bolts all together #12, #13, #14 but the list only includes #13 and #14. I thought there were only two bolts..
What I need appears to be #12 (front/lower bolt to which engine guard attaches).

13 90152-463-770 BOLT, FR. ENGINE HANGER
14 90153-371-000 BOLT, ENGINE HANGER (UPPER)

Index 12 and 13 are the same bolt. 12 is used on the standard, and 13 on the interstate and aspencade. Threaded on both ends and probably longer to accommodate attachment of the crash bars. 14 is the upper rear engine bolt.

Pretty sure upper is 10mm diameter and lower is 12mm diameter.

Thanks.
I currently use the bolt from CB750K which is about two inches too long but 12mm in diameter.
I thought I can finally use the proper length bolt but this seller gave me something else.

I will contact him for a refund.
