CB550F to dual caliper

Can anyone tell me where i can score a right caliper to match my existing left on my 1976 cb550F. I want to go to a dual caliper set up in front. I am sure this is a pretty common question. Any suggestions and options would be appreciated. Thanks

They are the same caliper, just switch the parts and bolt to the other side.
You can even use stock hardline, just loosen nut and rotate it 180 degrees
You may need to make spacers and do some filing on fork leg mounts as they were not machined at factory

Crazy
Thanks for the info. After i first posted this I sat there( with a beer in hand)and looked at the caliper and figured out that it could be taken apart and reversed. So, I went to the local parts bonepile and scored a caliper and disc. I appreciate it!

Godffery does these quite often.

Here are some pictures that might be helpful.
