Yes you will need a complete rod change system including the gear lever and the bracket Doug mentioned.
AFAIK they are not available new and you will need to source a used one but they are sometimes worn out.
if you can't find a rebuilt one at MM Coopertune/Steve here on the board rebuilds them with new bushings etc.

If in doubt, flat out. Colin Mc Rae MBE 1968-2007.

Give a car more power and it goes faster on the straights,
make a car lighter and it's faster everywhere. Colin Chapman.

If you purchased a rebuilt engine/gearbox from MM, it probably has a later rod-change gearbox.  Your MG-1100 engine will probably have the ADO16 version of the remote shift mechanism.  It is similar to but different from that used on the Mini.

MM makes a rod shift adapter for the floor tunnel.  However, you probably will need to source the rest of the rod-change shift mechanism as I doubt they included it with the rebuilt engine.  Give MM a call and see what they can do to provide a complete set of parts to make the conversion.

You would need to check if the crank throw is a problem but you might also be able to put your MG-1100 gearbox under the engine you just bought.  Again, I would discuss this with MM and have them help determine which is the best path forward for you.

I just pulled my 1968 Morris Mini MG1100 engine and see that the gear linkage is different on the old engine than my new one from Mini Mania.  Do I need to purchase a new gear linkage to use this?  Is there something I am missing?
