1970 duster with electric cut outs?

I am in the process of installing my TTI headers on my LA 360 engine, what a pain,! my question is has anyone installed electric cut outs (DOUG'S) on a Duster with TTI headers and TTI exhaust? I want to install the X style system and was wondering if any one else has already done it and what problems they may have ran into? Also, I do not have the passenger side header in YET, But, am I going to have issue's with Oil Filter Removal/Installation? I had to remove the filter so that I can install header and when I put header up in there to see how it fit, it looked like the only way I was going to be able to get filter in and out would be from up top, is that correct? Also, will it take a "special filter" (shorter)?

I was always told that with the TTI headers you do not need the oil filter adapter. I can not speak to the cut outs on an x pipe though.
