Our home was built in 1958 and the heating system has been glass heat panel throughout. Lately we have had a couple shatter on us. We have been able to replace them in the past but our supplier states that he is unable to get them anymore as the manufacturers have gone out of business in the USA and have relocated in Japan. The size we need is 14"x45" and 14"x31" by 1/4" thickness. Do you know where we could possibly purchace them? Thank you for your time. Mike
