depends on your engine mounting. If you just use the Trans-Dapt plates with SBC mounts and pads, then it's easy. If you use an LSx-specific tubular K, you're going to have a challenge. If you want a tubular K, get one for the SBC, then get the plates.

Then just get the plates. They're under $50 for the pair. I think the part number is 4692, IIRC

Your first post that started this thread made it seem like you had already found one. I think Spohn or BMR offer them, but I've never tried to order any such thing. Years ago, I made my own custom version. It was fun, but I just can't see any profit in it.
