1989 Heritage. Lost a bolt. Anyone know a place I can reliably look up a specific bolts dimensions so that I can just go grab what I need from the hardware store? Thanks.

 

Welcome to the forums from Ontario, Canada, may help if you tell us the area of the bolt.....

 

You may get more responses on the Evo sub-forum here:

PDFs of installation instructions for H-D Genuine Motor Accessories sometimes list bolt sizes. Otherwise I have to trawl the internet, which might only reveal the bolt thread so I have to measure the length of the hole myself.

 

Welcome aboard. More information would be helpful. There are a lot of bolts on these bikes.

 

Go to Ronnies parts finder and find the bolt in question
See if it appears on the list below
If not google the " Harley part # xxxx

 

The new HD OEM Service parts finder often lists the sizes of hardware along with the part number...

Additionally, if you have a Factory Parts Catalog for your year/model bike, there will be a "hardware list" by part number in the addendums, that shows the sizes of the various hardware mentioned in the catalog.
