I know a way how you can still watch the old boxrec.com page which shows the weights.

This is a way-back machine, a site which archives certain sites. So if you click on the link I post here, you can search boxrec how boxrec WAS and not how it is:

Let me know if this works for americans, because I am european and for me it works perfectly: the weight of all fighters is listed.
