Tach Dash and Bucket seat questions

[71stub]

I scored this tach/air pressure dash and passenger bucket seat out of a C70 this weekend a guy was going to crush for FREE! I thought it had a pair of factory buckets but the drivers side had clearly been replaced with a suspension seat by drilling holes in the floor. Anyway, Is there a replacement lens available for a Tach/Air dash? And is this passenger bucket the same as a Blazer? It hinges ahead on the front brackets and is pinned in place on the back. Thanks in advance.
