200R4 vs A518 vs Keisler A41 fitment

Using a bolt on bellhousing from either Reid or Quick Time to bolt on either a 2004R or 4L60 is only a phone call or a few clicks away.
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?
