Reading these prices

Starting prices aren't always comparable. Some include suspension, steering and brakes; some are a bare frame or front clip and the rest is extra. Check the Front and Rear columns and each product's notes before comparing totals. "Price on request" means the builder quotes each build. Confirm with the builder before you order, and send corrections through our contact page.

Upgrade the original chassis

How it's built
Body-on-frame ladder/perimeter frame with boxed front section, open C-channel rear rails and crossmembers
Front suspension
SLA A-arms with ball joints and coil springs; slow Saginaw recirculating-ball steering (manual or linkage-assist power)
Rear suspension
Live axle on semi-elliptic multi-leaf springs, open driveshaft
Weak spots
The open-channel rear frame and soft body mounts flex, and the steering is slow and vague. The front geometry gives positive camber in roll, and the soft leaves wrap and hop under modern power.
