Kicker L7 in a single cab 1993

[Mud Lover]

Hello everyone just bought my ranger and got it home a few days ago. So I flushed the engine, replace the spark plugs, changed the oil and filter, air filter and the battery. It had been sitting awhile and I am noticing this TICKING!! its a 3.0 liter v6 i did a compression test and the drivers side middle piston is about 15 pounds light. Just wondering if this was caused by a sticky rocker.... Anyways my big brother has a l7 in the garage that i can use and want to know if it can fit with the seat all the way forward becuase im 6.2. sorry about the conflicting problems but im new to the site and im excited to start my new project, i also soldered up my new deck up too today
