V6HQUTE, Mate I am almost 100% sure they are identical EXCEPT!!!!! smaller!! Reason I say this is a was a trade qualified motor trimmer for 7 years and have recovered many of both in the past. Gave up the job back in 2004 and can't for the life of me remember to be sure to be sure. Just called my old boss and he wasnt sure either (been years since he's recovered them) My advice. Call a local motor trimmer and check. Yes, the inserts or seat faces are covered differently too. Hope this help.... a little
