Official 3rd Gen Hemi thread

You have to move wiper motor inside under dash and make firewall flush or recess it a bit.

Are you taking about using a stock wiper motor or something like Specialty wipers (cable driven)? At the moment my plan is to recess the entire firewall 2-3 inches and use the stock location after the move. The Gen3 392 head interferes with the master cylinder hydra boost so if I recess the firewall it tends to solve both problems (I think)
