    I am currently working on a 68 T and C with 4 wheel drum brakes, 11 x 3 inch all around. I am considering installing disc brakes and have access to a single piston set up from a 1970 fury. Has anyone done a similar swap? What issues might come up? I am concerned about suspension geometry with the newer spindles, and hydraulic hose lengths and fitment.

    Suspension geometry stays the same as the upper and lower control arms are universal fit.. You will need a '68-'70 Bendix dual diaphragm booster unit to power the discs and the appropriate master cylinder. Calipers are the same from '69-'73. You will also need to install a brake proportioning valve and the appropriate tubing. Front disc brakes also take different hoses. The car will need wheel alignment. Disc brake rotor supply has been spotty but they are generally still available, you just might need to do some digging to find them. Be sure to install Timken bearings as the Chi-Com bearings are mostly crap.

    Thanks Dave. The car has the bendix booster already, and I have 2 more on the shelf rebuilt and ready to go. Ball joint shaft diameters are the same on the 68 and 70? I remember upper ball joints being different on something, but thinking thats an a body, right?

    GREAT T&C wagon...… good luck with the swap, and those LOOK like disc brake wheel covers.

    From what I can tell, the outer rings are the same as the Disc brake covers. I will just need to change the centers which denote Chrysler Disc Brakes with a red ring, IIRC.

    Hubcaps on his T&C denotes 15 inch.
    Those hubcaps and 15 inch wheels were optional on all models with drum brakes.
    The towing package came with 11X3 drums all around and did not have the self adjuster cables.
    The drums & backing plates are worth some money to a guy building a Hemi Road Runner,Charger,or Super Bee.

    That's right - you could get 15" wheels with DRUM brakes and you got a VERY similar wheelcover with them. Beautiful T&C that looks great with those wheel covers. When the conversion it will stop just as nicely as it looks.
