The filter mounting threads broke on the end of my 75-300mm III lens. All I need is a new plastic ring that screws onto the end of the lens. I am unable to use my lens cap or lens hood

A professional repair might cost more than the lens is worth. That lens routinely sells for less than $100 on ebay. 75-300mm III SOLD on ebay
You might be able to buy the part for about $19 and replace it yourself. It looks like it just unscrews...
It might also be a good excuse to upgrade. You could sell the 75-300 for what ever you can get, and then buy a used 55-250 IS for about $150. The 55-250 is optically better AND had image stabilization.
Is this what your lens looks like now?

I'd either super glue the hood in place or follow Mike's advice and upgrade. It's not worth repairing. I saw a refurbished 55-250 for just over $100 the other day. Canon's website is down otherwise I'd link it. Refurbished to original specs, with warranty, for a much better lens. There's no

Was readng your thread until I got to the "sanding" part. Mike's part link above still shows as available.$20. eBay has these as well under $100. I don't buy this type of equipment from eBay myself, but you are free to choose.
I saw a fully working replacement (refurb) on Amazon (super cheap) and Canon still sells MkIII $159. Or simply upgrade. The 75-300 was a workhorse in its day, but has been surpassed in quality, function and IQ.
