It appears that your part numbers 21-001, 21-007, and 21-154 could replace the parts in the attached photographs. I assume the guide pins would also fit the upper and lower door tracks.
Could you please confirm all of this before I order?
Thank you

If your bifold pins are 5/16" thick, you can use either just the pin and cap with our 21-005 along with your existing springs, or our 21-065 complete set. Your pivot rod clamps look fine, but if you want to replace them you can use our newer style 21-154. I think the 21-001 bottom may be a good replacement option for your bottom threaded pivot pin, but I would like to see yours to confirm.
