Waiting for the water co. to come and change my meter so I am bored.
The front inner and outer bumpers are the same (have them on my mm bulkhead + plastic). Center plastic is the same, shroud around the gas tank is the same, looks like the bulk head, side panels, and hood are the only major differences. I bet it's an easy swap....
I'd pm betheviper. I know he has made some interesting combinations over the years and has broken down and parted lots. If I remember one of his posts from way back correctly, I think the motor mounts are different between the mm (redhead) and srx/viper. To put the srx motor AND stock pipes in a mm/sx chassis you had to swap the hood, side panels, AND bulkhead so everything would bolt up, or make custom front motor mounts and do something different with the factory tripples. Don't quote me, I just remember reading something to this effect back when I was considering a srx block instead of my redhead in my mod.
