punkoutnz Posted March 25, 2015 Share Posted March 25, 2015 Closest measurement I can get on the sides is 41mm, bloody hard to get vernier calipers in there and mine are metric, haha. Quote Link to comment Share on other sites More sharing options...
Kiwibirdman Posted March 26, 2015 Share Posted March 26, 2015 The size should be stamped on the frost plugs, can be hard to read if they are rusty. Frost plugs come in all sorts of odd ball sizes, the ones in mu firebird were some thing like 1 61/64 inch. The expression on the young guys face at Repco when I asked that size was priceless. In comparison the girl at Partmaster didn't flinch when I asked the same question, and only took a couple of minutes to say they weren't in stock in the store but they would have some in 2 days.
