the stock fan is taken out of the lower box side of the HVAC unit....the vlower section is then cut off and tossed. The fan is then installed in the Haggard fab blower box and the assembly is then attached to the HVAC unit. It rotates the fan 90 deg and nets a substantial increase in room between the fan and firewall to clear any size tub.....only downside thats not really a downside is it eliminates the outside air from coming in through the cowl so you would have to patch that hole...its not a big deal at all...your A\C will pretty much be on recirculate the entire time.
