You can mount the Gila to A3 cases but the transfers need welding in the magneto side and clutch side, not just the sealing face of the cases. It’s a lot especially for the welder. I don’t even weld my cases anymore and leave it to somebody I trust and that’s easy to work with.
A35 can except a Gila with just welding the transfer area face and matching it as normal without blowing through the case sides. Just have to use care. I ain’t never seen two types of A35 cases as stated above. A55 cases are pretty much turn key when fitted with Gilardoni.
A35 only welded on the face. Street mate.
Look up Jake Cain’s TOBY build, also “Quickly” for clutch stuff
