Now that's interesting. I never knew the 545RFE and 46RH(E) used the same mount. So if you can score a junkyard crossmember from an overdrive equipped truck and want to use the 545RFE, as I did, you're golden. The shift linkage for the 545RFE requires fabrication, (which S&P DIDN'T do) unless you want drive on the shift quadrant to show up as neutral. Essentially, without a little fabrication the entire shift range shows up as park through drive (that would be first gear) on the quadrant and the effort to shift is high.

The drivers side requires headers, or a Jeep Grand Cherokee drivers side exhaust manifold, most anything fits the passenger side. They cut the top flange of my frame trying to get the truck manifold to fit.

I believe my engine was in the stock position, so the 45 degree adapter wasn't ever an issue for me. Since my engine was '07, it could use ANY of the older mopar or Ford filters. 2008 they changed the pipe size to metric.

The rest is pretty much wiring, save for the PS pump. Pressure is too high for the old box. I "think" they used a GM pump and did use a custom remote reservoir, which I hated, because it leaked, not terribly, just enough to be really annoying and have to top off periodically.

Almost forgot, I lost my cruise control, later S&P (read: hotwireauto) told me they figured out how to make it work, but I never pursued it. I was completely fed up with their antics by then.

I hope they've come up with a good way to drive the speedometer, I got sick of the wonky electronic adapter they used and mounted a GPS.
