altercation vs hemi denny

I'll chime in, I love my HDK. I can attest to how well built it is and how my car handles / drives. I didn't have to buy any special wheels with different back spacing which saved a boat load of cash. The setup is less expensive than the RMS also. My Demon will be the 3rd A-body that I have used the HDK and for me its a no brainier. All 3 had to be special built for each application. The Hemi Duster was a 5 speed, the 1968 Hemi barracuda was installed with a motor plate so the HDK was really easy to use and the Demon was different in that I wanted to use the factory heater - A/C box with a really big blower motor, I also wanted to use a power rack with a FLAT hood. Fits like a glove. Just my 2 cents.
