Andrew I Don,t recall if this one had a hardware change or not, The red one pictured Is a twenty year old kit kadet that I prepared for the gentleman and its very likely I just used a Dave Brown mount and drilled it where it needed to be. The LA-65 is being used on four Kaydets at our field and they working out very well indeed.

On the arf version I am not sure is it comes with some sort of adjustable or the old standard Sig Two piece metal mounts. It they are the two piece there should be no problems in mounting the engine even if you have to redrill.
