how does one change out this one, done several, but not looking forward to this!! any ideas?

i'm not sure if i'll be of any help, but i just did mine (93 s-10 pick-up)... it wasn't too bad once all the bolts were out..... it's right up against the firewall, but it was really awkward to get off some of the bolts. it took a few hours, but not bad. i just bought a haynes manual, and went for it. I don't know the changes that occured in 94... but i do know there were quite a few... i hope i helped anyway!!!
