Who is this "They" that I am mentioning and why don't they make the parts, Is is a conspiracy?
Sorry, this post got kinda long, I hope you stick with me.

Thanks 280EXRider...I new I forgot to ask something and your answer was to the question I forgot.
The pods are getting replaced, the heater core, all of the mentioned A/C components one of which is the all aluminum ACM evaporator with a pre-installed expansion valve, and all new seals.
So what about the hoses? Should I keep using them as long as there are no holes in them? If I do need new ones can't a local business make me some new ones at a much lower price than the ones available online.

Ironically the later 124 cars that came with R-134a from the factory have among the better a/c systems I've experienced; they really make a lot of cold air, even a idle on a 100F day.

If the piping and hoses are the only with the install, as mentioned above, I could find a local shop to make the necessary hoses.
Now, as far as the duel fans, What can be done to put dual fans in?
Also, If the later W124 cars came from the factory with R-134a and works good why can those parts be used, purchased, and made to work???
Hopefully this week I can find some time to do whatever needs to be done so I can purchase R12. I have been reading many threads and it does seem the way to go and I will probably go that route....but I like tinkering and the idea of making a different compressor working or pulling a system from one model year to another is just calling me (like I need another project)
Is it believed that if the early W124's (with r12 and completely stock) had dual fans that it could make a big difference in the cooling. From a comment above it seems like that was implied, but how many changes did they make to the A/C system.
