Richard,  Those are humongous electrolytics!  The unit must weigh a ton. How old is the unit?  Also, where do you get the push-button switches? Should be able to get a nice chrome washer to cover the damage they did to the hole.  I too buy mostly from Mouser and use the project feature.  I also use the projects to keep "wishlist" items.  Have you tried RS https://us.rs-online.com/ ?  It is the old Allied, and you can find some very good deals on caps and resistors.  Keep the photos coming!  Joe
