Chassis stiffening

1968–73 Datsun 510 chassis stiffening

2 kits to stiffen the body shell, from frame rails and connectors to braces and roll bars.

How it's built
Steel unibody
Weak spots
Strut towers, floor pans, rocker panels, rear quarter panels and the trunk floor rust. The R160 differential and rubber-bushed semi-trailing arms are the weak links when power goes up, and the steering box and idler arm wear and get loose.
