A C-10 cab has no back seat, and it is a fairly small cab. When installing seat belts the mounting location is critical. The driver, passenger, and middle passenger can share the same lap-belt floor-mounting locations. But, it is advised to mount them separately. The mounting locations of the lap belt is very important, if it is located incorrectly it can cause serious damage to internal organs. During forward impact, the lap belt should pull down and back.

When installing the restraint mounting anchor hardware to the vehicle floor, it is important to minimize bending stress in the mounting brackets. This is achieved by making sure the lap belts pull from a straight angle against the hardware. The attachment and anchoring points must provide optimum geometry to minimize movement of the lap belt. The lap belts will perform best when it is installed at an angle between 45 and 55 degrees, relative to the longitudinal axis (floor) of the vehicle. This angle permits the lap belt to react to the upward pull of the shoulder harness.

The end attachments of the shoulder harness must also be installed at the appropriate angles. The ideal position is anywhere between 5 degrees below and 30 degrees above the driver's shoulders. The shoulder straps should be 3 to 6 inches apart, behind the person's neck to prevent slippage off the shoulders.

The shoulder harnesses and lap are connected by an automotive flap latch, latch 'n' link, compact-cam-lock, or twist-cam-lock.

There are also three-point; similar to the lap and sash that were used in the '60s and '70s. The three-point and lap-and-sash belts helped spread the energy of the moving body in a collision over the chest, pelvis, and shoulders.

Truckin',
Can you tell me where I could get the bullet door handles that are featured in the 2006 "Rookie of the Year" Ford truck photo
Thanks,
Amy Cohron

Amy,
The truck you are referring to as the "Rookie of the Year" was featured in Truckin', Volume 33, No. 11, on pages 94-101. Young gun 15-year-old Shane DeBerti and his dad, Doug DeBerti, co-built the '06 Ford F-150 4x4. The door handles were manufactured by Grippin' Billet, www.grippinbillet.com, in Fresno, California, (PN 12019) Slinger with nickel bullets.

Truckin',
Not too many years ago, Truckin' had a tech article on the best performance exhaust. Brand X versus someone else, and I can't remember the other competitor. This would not be bad, except I am looking for a great performing set of headers. I have the last year 454ci V-8. No, I do not want a diesel. My truck is paid for and I love it. It does all I need and then some. But now I want performance. At least, please direct me where I can find exact replacement performance headers because I cannot find any.
Thanks

Hi Brian,
The last year of the Chevrolet 454ci V-8 engine was offered was '00. If you were looking for a set of good headers, we would look at Doug Thorley or Holley's FlowTech Headers. The Try-Y header will give a better flow velocity.

Dear Truckin',
I have an '07 GMC Sierra Crew Cab and I'm looking for ground effects or side skirts. I found some Street Scene side skirts, but they are only for regular and extended cabs. Do you know of anybody who can make those fit on my truck, or anyone who can make me some custom side skirts, or when Street Scene will have them available for my truck?Thanks,
Eduardo Soto,
Alton, TX
