Complete 3 Speed.... Your thoughts !!!!

Why not find out what's wrong with it? My 64 Valiant is 3 on the tree and I love driving it.
There is nothing wrong with my transmission other than the first gear does not have synchros which is bad for solo II events. So I’m looking for the A230 as I don’t have to double clutch or come to a complete stop to get it back in first.
