Attention: TDR Forum Junkies 
I was reading the thread on making the cat hollow and one of the posts there was talking about the emissions dyno.
Here is some info that might be of use.
I have driven a couple of tightly setup auto CTD Dodge trucks thanks to members here. I would certainly not put them on a dyno without chains or straps. The things are hard enough to keep straight on the dry road.
In CT, they used to just drop your front wheels into a dip and lift the back with a dyno about 4 or 5 inches.
The trucks I drove would have jumped right out of the wells when they shifted.
I took my Cummins A series powered van (God, I miss it
) into emissions. I did not want anyone else to drive it.
I told the guy it was a custom truck with a "pulling transmission that would likely jump right off the dyno" (Truly it was 125 HP and an old AOD which shifted like slush but it was MY truck, not the state of CT's)
The supervisor came out looked under the hood, scratched his head, looked at me, scratched his head some more, asked me if I was strange or something, then came back with a pass sticker and told me to have a nice day.
"I'm not going to risk anyone getting hurt," he said.
Might be a way for you guys to avoid the whole mess. "Pulling transmission" is a buzzword for them.
I found out from an insurance buddy that someone was hurt during the dyno of a truck set up to pull trailers (Like a hot shot) when it shifted hard and jumped off the dyno. The insurers sent out a memo (to the CT folks at least) telling them not to test any vehicle modified in the trans department for towing.
If you are nervous about being put through the test, just go in with the attitude like you "dont want to see anyone get hurt". Chances are, if they look in and see a few guages, the wont touch your truck. If they do, you haven't lost anything!
Hope this works for you!
