Replacing heater blower motor in 69 Chevelle w/SBC

[vjjack04]

Hey folks,
I am new here. I am working on a fella's 1969 Chevelle (SS Clone) and need some help. I will be replacing the blower motor for the heater. I know its under the passenger front fender area, but the only examples on You Tube show cars with a plastic fender liner in the wheel well. This one has a metal one. So, I suppose I must remove it completely to get to the fan. Can that be done while leaving the outer fender in place? Thanks for any assistance, advice or tips.
