- Drive type. If your car is all-wheel drive, make sure the part is for all-wheel drive, not rear-wheel drive.
- Engine size. For engine parts, make sure the engine size on the product matches your engine.
- Transmission. Manual and automatic cars often take different parts.
- Body style. Sedan or hatch, two-door or four-door, cab and bed length on trucks.

UMI Performance offers an on-car adjustable control arm for the rear of the GM B-Body vehicle. This rear upper control arm for the 65-66 GM B-Body is a direct replacement for the factory arms and is designed to minimize wheel hop, improve corning, and help track consistency. It allows for easy pinion angle adjustments without the need to remove it from the vehicle. The control arm features greaseable bushings, TIG welded construction, and a 4140 heat treated Chrome-Moly adjuster. Please verify whether your vehicle has (1) or (2) upper control arms. Six cylinder and most small block vehicles were supplied with a 3-link rear suspension while big block vehicles used a 4-link set-up.
