Hi. I bought a truflex rear bumper cover from Ken’s Corvettes a few years ago. I liked the truflex because it was more rigid than the original urethane (no waves and no cracking with age) and more flexible than fibreglass (no cracking in case of a gentle bump). Because all C3 Corvettes vary marginally in size due to varying humidity, temperatures etc. when body components are being molded these bumpers are made slightly smaller. This avoids the need to repaint fenders (or perhaps the entire car) as would be the case if they were too large and you had to build up the fenders. You may get lucky and find it fits your car acceptably but more than likely you’ll need to use some flexible body filler and lots of patient sanding. They mount with stainless steel fasteners, no need for the original mounting strips. Follow the provided instructions, be patient and you’ll get a satisfying result. Hope this helps.
