I have worked on my 300d and replace the evaportaor core ALL day long. I put the core back in and the dash is up... I can not figure out how to re-attach the evaporator core tubes that go through the firewall and attach back in the engine area. It takes all I have to just reach the 2 conecting points and stick them up to the tubes (using a screw driver and pliers) coming into the engine area from the core. Then some how in the minature area I am suposed to screw it together. I can't see any possible way to get a screw driver in that space? Any ideas? Do I need to take some of the engine apart in order put one screw in? I am about to go crazy!

Thanks for any ideas.
