I have a set of 340 biscuit type mounts, $50.00. I am pretty sure they are the same. Maybe someone on the forum can confirm the interchange. PM for more information.
Do you need the B/E body or the A body? They are different. Brackets or rubbers? AutoZone has the rubber mounts for abou $5 each.
This is what the 340/360 A body looks like.Sorry, I do NOT have a set right now.
