Handlebars question for 1970 Bonneville

I have a 1970 Bonneville. The handlebars it came with are definitely wrong. In looking in my parts book I can easily track down the part number of the handlebars that originally came with the bike. These are the handlebars I'm looking for. I'm concerned with going to swap meets and looking for these and wondering if there is any differences between 1970 and other years. You'd think they'd use the same bars for many of the bikes. When I compare part numbers for 1970 vs other years, the part numbers are different. Yet other years can have the same part numbers for their handlebars, like 1966 and 1967. I'm half tempted to just buy new from a parts supplier to ensure I get the right handlebars. I've gone to swap meets before and bought parts for what I was told would fit my year bike and then to get home and find minor differences to where the part doesn't fit. So the question is....are these handlebars all alike? From what year to what year will I find handlebars that came stock in 1970?
Thanks.

I think I found the answer to my own question. I looked on MAPcycle and found handlebars. It lists groups of years for particular part numbers. All I had to do was know my part number. 1970 Triumph Bonneville handlebars = H1870. Now the next question is....Predrilled holes or no predrilled holes. I'm guessing this is for the Horn push & Dip switch. Any thoughts?

I never say "have you got a XXX for a YYY?" at auto jumbles, (unless I trust the guy) I always ask "What does this fit?"

Otherwise the seller can give you any old junk to get some dosh. He' should know what bit fits what, unless it's a guy selling a clearance lot

Answer is buy the bars that are comfortable for you when riding. Buy them undrilled so you can mount the dipper/horn switch where you want them. Drilling the 2 holes is no big thing. Like salesmen at swap meets catalogs can be wrong also.

My 1970 Bonnie with what I assume are the original bars has the horn push/dip switch mounted to holes drilled in the bar. The position works fine.

Thank you Bruce. I was wondering how it originally came in 70.

Has anyone found a decent way of mounting the horn button without drilling the bars?

I'm trying to dial in the alignment of some M style bars I just got and don't want to drill until I'm sure. In the meantime I've zip tied the button but it's not secure enough to actually use the dimmer switch.

thanks in advance!

Look around for universal clamp on switch or modify a later right hand switch gear.

Thanks! Here are some pics with the new Norman Hyde M style bars. The mirror doesn't work very well in this position no matter how much I adjust - anyone point me to one that might have a different rise?
