yea some of them had the bolted tunnels some didnt, all i know is it makes doing that kinda work a HELL of a lot easier, so easy to get to the top bell housing bolts with that cover off on my 84 i had, but my 86 pickup doesnt have the removable tunnel, not that i plan on putting a tranny in it anytime soon ..lol..but would be nice..i say cut the thing off and put bolts on it then use something to seal it up..would probobly make future tranny removale/installation much easier..
