This is a complete bolt in LS adjustable conversion engine mount kit for 1970-83 240Z, 260Z, 280Z and 280ZX non turbo. These are direct fit using the stock Z front cross member utilizing the stock engine mounting pads. Dirty Dingo Adjustable LS Conversion Mounts are precision CNC laser-cut from .250 thick 1050 High Carbon cold-rolled steel. Specifically designed for the Gen III/IV LS series engine installation into older GM muscle cars, these LS adjustable conversion mounts are slotted for optimal adjustment in the engine compartment. These mounts will allow you to move the engine from the original bell housing position up to 2 1/2” forward and 1/2” rearward and ensure secure engine placement when torqued in place, even in high horsepower applications. Each mount is manufactured using precision CNC press brake with a custom large radius die to minimize stress on bends. Conversion mounts are designed to integrate with the factory rubber clamshell-style mounts on the original frame. The design accommodates a range of standard or automatic transmissions, including Powerglide, TH350, TH400, TH700R4, 4L60E, 4L65E, 4L70 and 4L80. Each kit includes high quality grade-8 zinc-coated hardware, including new cross bolts.
