Two ways to buy this kit
Universal — core kit, $1,390. The A/B/C adapter core itself: what physically joins your engine to the transmission. This is the right choice for a resto-mod, a custom chassis, or any build where you are making your own mounts and plumbing.
Complete kit. The same core plus every chassis-specific part for that vehicle — mounts, cooler adapter, lines, shifter and park-release hardware. Everything below is itemised at its normal individual price, so you can see exactly what you are getting and check it against our other listings.
