You can pick up original blister/bubbles with patience and time via sales on the forum and ebay, and then be able to Reseal your figures for your own collection.
Putting a new generic bubble with a vintage card and figure is not the way to go for collectors, as this is creating something that ends up not being vintage, and there are many unscrupulous people out there that would do this and dry to dupe the completely innocent buyers coming into collecting. I am in no way insinuating that this is what you are doing, but highlighting the point, as this would be the reason you will not get any positive reaction on here or any other vintage forum to new or reproduction bubbles.
As an alternative you can buy an acrylic case in which you display the card and the figure together without a bubble, keeping the components original and protecting them ( which is one of your pre requisites)
Why noy take some pictures of your collection and pop them on a limelight thread on here, so we can enjoy a look at them, and assist with any advice you are looking for, we are a nice lot of guys, that are passionate about vintage.
Hope this helps
