Has any1 done this mod?
What are the dramas?

Any help appreciated
Have seen on marlins site there setup for the dual case and bolted upto the chain case after anyone know anythin about this 1.
Also if anyone has a dual setup for sale let me know.
Thanks Bull

you best bet would be to email the ppl at marlin cralwer and let them know what you want to do, it will also help if you have your gearbox model to tell them and theymight be able to help you
