Should be the same plug as a A[?] 32, the 'R' is a resistor plug, at least thats the way plugs were listed in the past but with the way plugs and their listings have changed I could be wrong. The old Ford/Auto-Lite numbering system would signify a A=14mm-R=resistor-32=heat range.
I haven't been coming on here much anymore as my BBF projects are all "done", but holy cow, is there any moderators left? I'm trying to help out by reporting spammers as I come back, but wow, there's a TON of them, and it seems like some that I report go unnoticed for days or weeks.
