hello everyone. i'm a total newbie. i put apart an old marlin 6 and want to put it back together with new parts. i could buy new versions of the same parts and be done with it, but i want to know how far i can take meddling with the original design.

Photos of the marlin 6 ?

Do you possibly mean 'Marin" ?

i'm pretty sure i mean the trek marlin 6

Hola, and have fun. Park Tool's youtube channel is an amazing resource if you want to learn quick.
