Larson "Brass" Exterior Lock and Handset

I have a fairly old Larson Door, Magna-Core 239-GB. I don't have a registration number on the door. The brass color has deteriorated on 2 parts which I would like to replace: Larson Part # 20217911 Outside Lever Assembly (WP Part # 00116) and Larson Part Number 20217912 Outside Deadbolt Assembly (WP Part # 00101) (with lock). I'm not sure what the WP Part Number is. I contacted Larson and they only have a general replacement part kit which would require either new holes with backup plates which are way too big for my door or, if I don't use the plates, the new hardware won't cover the areas which have been scratched from the old hardware (basically the new hardware is smaller than the old but the holes appear to line up). I hope you can help me. I really want to get exact replacements if any are available. Thank you

Thanks for your reply. The more I looked through your website, the more I think your product 40-058 will work. Here's a photo of my door hardware.

Your 40-058 handle & deadbolt set worked perfectly on my Larsen Magna-Core 239-GB storm door (7/8" thick) circa 1996). In my case I had to use some of the catch ("strike") spacers as additional interior spacers for the deadbolt (I drilled some screw holes to align with factory spacer), but otherwise everything was a perfect fit! The Swisco looks to be very sturdy and of very high quality, too. Fast processing and shipping as well, even with pandemic lock-downs. Thanks!
