Nos 1968 Super Stock Hemi Transmission

This would make it unstreetable.
For a streeter,you would HAVE to put the brass rings back in, and depending on what else was modded, probably the complete synchronizer assemblies. Not a deal breaker; but the engineering in this box is hard to justify for street use.
For a streeter, there are other options. This has been detailed on FABO,search it out or PM me.
You are correct. I'm not expecting someone that wants to buy this to run it on the street. This is a very rare perfect piece for a high dollar Nostalgic Super Stock restoration car.
