While refurbishing the entire A/C system on my '85 3.2, i made the newbie mistake of connecting the receiver drier to the a/c hoses about 2 weeks ago and am about a week away from pulling a vacuum and then charging the system.

All that said, the system is essentially 'closed' as all the a/c system hoses are connected to their respective components, but since the drier was in essence exposed to the elements of air during this time, albeit the small amount that's floating around in the barrier hoses, do I need to replace the drier, and if so, what are everyone's thoughts on the $39 Uro brand, vs. Kuehl's $69, vs. Hansa's $150 version (i'm not considering the ProCool due to price).

Thanks to all in advance for your feedback.
