Product Description
A three-point retractable seat belt is a big safety upgrade for a classic car, but the belt itself is only half the job. It has to be anchored with the right hardware at the floor and at the retractor. Seatbelt Planet Hardware Kit #1 is built specifically for one 3-point lap and shoulder retractable belt, so you have matched, correctly graded parts in one package instead of a coffee can of mismatched bolts.
What Is in the Kit
Seatbelt Planet lists the contents of Kit #1 as:
- 2 x 7/16"-20 x 1" bolts
- 2 x 7/16"-20 x 1.5" bolts
- 4 x 7/16" hex nuts
- 4 x lock washers
- 2 x 2.5" reinforcement plates
- 2 x 1" angled floor brackets with a 90-degree angle
- Grade 5 strength hardware
The 7/16"-20 fine thread is the standard size for seat belt anchors, and Grade 5 hardware is a common strength rating for seat belt mounting. Seatbelt Planet notes that its hardware is engineered for seat belt use.
How the Parts Are Used
A typical 3-point retractable belt has a retractor end, a lap anchor end and a buckle. The angled floor brackets let you mount a retractor or end fitting so it sits at the right angle, which matters because retractors rely on their orientation to lock correctly. The reinforcement plates go on the underside of the floor to spread the load across a wider area of sheet metal, so a bolt cannot pull through thin metal in a crash. The two bolt lengths give you options for different stack-ups of bracket, belt fitting and floor thickness.
One Kit Per Belt
This kit is sized for a single 3-point retractable belt. If you are installing belts on both front seats, plan on two kits. Many Seatbelt Planet belts list "proper mounting hardware kits available", and Kit #1 is the match for their universal 3-point retractable belts.
When You Need It
- Your new belt does not include mounting hardware
- You are adding 3-point belts to a car that only had lap belts
- The original bolts are rusted, stretched or the wrong grade
- You are building a custom or hot rod interior with new anchor points
Installation Tips
Pick mounting points on solid, rust-free metal and check underneath before drilling so you do not hit brake lines, fuel lines or wiring. Mount the reinforcement plate on the far side of the panel, use a lock washer under each nut and tighten every bolt securely. Position the retractor at the angle its instructions call for and make sure the webbing feeds without twisting. Test the retractor with a sharp pull before driving. If you are not sure the floor is strong enough, have a qualified shop inspect it.
Using the correct hardware is one of the easiest ways to make sure a seat belt installation does its job. It is a small part of the project, but it is the part that holds everything together.
