1960-72 Rear Trailing Arm Bushings (Poly-Graphite Upgrade)
With Early Classic's One-Piece Side Window Kit, you can eliminate your '67-'72 truck's vent windows and give it a cleaner appearance. This kit includes clear glass and all necessary hardware to complete two doors. The installation of these kits are fairly involved requiring the removal of both doors along with some cutting and drilling. (These items ship UPS Oversize 2 Class, and bill for shipping at 70 lb.)
Got Horsepower? Early Classic's new Trailing Arm Reinforcement Kit is what you need. This kit consists of two pairs of laser cut upper and lower reinforcement plates, polygraphite bushings, all necessary mounting hardware, and new U-bolts, allowing you to upgrade and rebuild at the same time. While installation does require welding, this kit will give you a much stronger rear suspension capable of handling most anything you can throw at it!
