Maker and Model: The rear 2/3 is the Ulrich Challenger Chassis Comments: The front 1/3 is an MMRC addition.
If I get a proper Ulrich front end, I'll put it here.
Fully independent rear suspension with coil springs and universal joints.
See Auto World catalog, 1967, p 121.
(Note the AW 1966 catalog has the pictures of the Ulrich Sprint and Challenger reversed.)
