I proudly have and use ROLLGUY's A/C conversion in my MB. However, those thick rubber lines are for the birds.

So, has anyone simply replaced them with aluminum tubing? I was thinking of running them "straight" from the compressor, then 90* bend at the radiator cradle, run along the bottom area of the radiator, then another 90* bend towards the firewall, then up and then tuck them away on top of the inner fender. I cannot think of a way to hide them completely, but it will certainly get them out of the way. The SAE to metric fittings might be tricky, but looking at all new or newer cars, they have all aluminum.

Any thoughts ?
