** NOTE***

Depending on what has been done to your engine over the years you may need to move the windshield washer fluid tank and re route those lines.
The stock air filter that came with the v6 engines is a haus and you may need to convert to an aftermarket air cleaner to be able to get the clearance you need to install the kit.
The booster conversion kit is not OE style and is an after market product.
The brake line tube nuts will not automatically screw in to the master cylinder and adapters will be needed. Our suggestion is to splice in a jumper line from the old location of the manual master cylinder on the firewall and run the lines the 15.5" inches you need to make it to the master.
If you have a larger battery than what came stock with your car the unit may be 1" too long and may need to get a smaller battery to get the unit to fit.

According to the installation instructions, the power booster seems to create the potential for clearance issues with washer tanks, batteries, and with an extended 4 bbl manifold, potentiallly that as well. Currently has manual drums. Disk upgrade is a plus. Is this kit available in a non-power boosted option?
