Not that I can help, but your question itself does not provide enough information for others. What you state to be the pattern (PIR 88) is in fact [b]not[/b] the pattern ID or original manufacturer code … it is merely the stock code of replacements.com and thus utterly meaningless to others.

Your question should therefore contain info in the direction of [i]”… I do not know the original pattern name or number, but I found a match listed at replaments.com as ‘PIR88’ …”[/i] simply to avoid confusion.
