Great quality terrible product.

The materials are top notch as typical for Dirty Dingo. Precision cut, good clean finish, and the hardware quality is phenomenal! If you think it kinda looks like a torture device with all the fancy hardware everywhere, you'd be right. This is one of the least pleasant aftermarket parts I've had to install, and that's what I do for a living. Depending on your accessory drive and engine placement you have to assemble everything to just to figure out where you need to drill the holes. Then you get to undo that, paint it, re-do that, and then undo and re-do that again when you have to cut up your painted parts after realizing that there is severe interference with factory brake lines that weren't installed at the time of the initial mockup. But don't worry, you could get to do that again if you didn't read the instructions before purchasing that it was only designed to work with a Holley low-profile oil pan. I realize that it sounds like im blowing this out out of proportion, but please realize this kit includes 12 plates, 45 bolts, 45 nuts, 90 washers, and 5 spacers. That is a total of 197 things that I had the displeasure of handling 6 times which makes a total of 1,182 things. That's too many things. I feel like the Geneva convention made rules against this type of stuff. If my boss ever orders one of these again I will quit on the spot and probably bang his wife so he understands my pain. Final product looks good.

Could be better

No directions included, directions once printed off the website could be better. Not very clear where the engine should be located

Thanks for the feedback. The conversion mounts are sliders, to allow flexibility of where you want the engine placed. You can set the engine where it fits best for you, as no 2 applications are identical.
