I spoke with Ross from QuickTime a while back about getting a custom bellhousing made. He told me that as long as he had both of the pieces, the block end and the trans end, he could pretty much build anything. That is how I ended up with an adapter to go from a small block mopar to the 4l80e. Quicktime/Lakewood does offer a bellhousing for the aod/aode,
Quick Time Rm-9061. When I spoke with Lakewood at a show over the summer I asked if they could custom make a bellhousing like Ross had for me and was told that they could. So, yes, a bellhousing is available. Again, it will not be inexpensive, I think I paid $650 or so for my SBM/4l80e piece. The aode/4r70w can be built to take some abuse, my buddy has built a few of them for some off road racers that have held up just fine......
