I don't see any 200r4 bells on QT's website anymore and Reid doesn't have a bell specifically for the 200r4, but I did see Extreme Automatics is making an adapter ring to adapt a Reid to the 200r4. I would suspect using an adapter ring is going to locate the transmission further back, adding to clearance concerns?
The Gen 3 Hemi and the small block Mopar use the same bell housing. I just bought a Quick Time bell to adapt a 4L60 to a small block Magnum and several years of the 4L60's come with a bolt on bellhousing.
Extreme Automatics adapter ring bolts onto the front pump cover of the 2004R allowing a Reid bellhousing to be bolted on using the adapter ring. This obviously necessitates cutting off the original bellhousing on the 2004R's, but it's not hard to do that yourself. If it does move the transmission back farther, it would only be about a 1/2 to 3/4 of an inch, the thickness of the adapter ring).
