Looking at a Rampage.

It's my understanding the chassis is based on the omni/horizon platform so the from suspension from those will work, correct?

As for the body will the front clip interchange?
Doors?
Will the 5 lug hubs & rear disks from the Spirit/Daytona platform swap over?

Any thing else from the Spirit/Daytona work?

I want it to be a daily driver since I need a light truck and better gas mileage too. But if I can't keep it alive then it may not be worth it.

It all drops right in.

The Daytona/G-body panels won't fit but the mechanicals interchange.

Some people would retrofit the early minivan front disc brakes and the Shelby/CS Daytona rear discs.

I did those swaps on my Shelby Charger.

Suspension is the same from the omni/horizon but none of the body parts will interchange. The charger/turismo share everything from the doors forward with the rampage. So you can take a shelby charger front air dam and turbo bulge hood and put them on a rampage.

My 81 Charger 2.2 was under braked from the factory. I bought a Mopar Performance or Direct Connection kit. It came with a ventilated disc, bigger calipers, semi metallic pads, and a bigger MC. Price on that was a fuzz under $300. AFAIK it was all Daytona stuff. Only difference was the pads were ground on the edge to eliminate squeeling that was inherent on the Daytonas!

Parts guy got a kick out of the price, and my knowledge that such a kit existed.
