djed50,
you will need an adapter as the original bolted to the frame and if you look at the bolt holes on the MC you are talking about, it does not bolt to the original location but paralel to the frame on an adapter. classicperform.com has some great installation info and exploded views on this in there tech section. you would also need to run seperate lines to each chamber of the new MC. vwnate1 gave me the idea to get rid of the T junction that splits front/rear lines and get a couple of elbows and then run your own lines to the MC. just picked them up from FLAPS....looks like they will work great.
