So, the AC shop found a huge leak in the condenser. They were having some difficulty finding one for mine at thier usual sources and said I could shop out there. I am also trying to do this on a limited budget due to wife working part time. I have 2 and possibly three options.

I can get a factory one from Tasca Volvo for what is a listed price of $393.50

I can get an unk repro from FCP Groton for $194.51

I can possibly get a used one from a local junkyard. This is predicated on whether this one out of a 93 960 is the same part number.

My Car's VIN ends in P1058841 From what I have reading, cars with VIN's before 1081227 require a different condenser which is both more expensive and also harder to get. FPC lists the part number as 3537971

Thoughts??

Avoid a used one, given the cost of again repairing a leak. I would go with a branded unit like Four Seasons from an online auto ac retailer.

See the 700/900 FAQ at the drop-down menu above right.

Most retailers do not list the maker. Do you know who carries the Four Seasons brand?

I may have been lucky but I have used 3 used ones in various cars, and have another car that had a used one installed before I got it, with good results. I always got new o-rings though.
93 may be a crossover year, with different methods of attaching the lines at the pass side bottom of the condenser. Older ones had two separate lines that connect separately, newer have both lines joined to a plate that bolts as a unit to a diagonal surface on that corner. I have seen both on 93 cars.
The PnP interchange list shows some to not fit, but they do if you check the details.
I have used both NA 940 condenser in a Turbo, and a 960 condenser in the same Turbo. They are the same, so if the lines mount the same way then you're good.
Or, you could change the lines.
I think they all have a sort of cutout on the top driver's side, that is to clear the air intake on NA cars, but you might check if that is there or not. One with the cutout will fit any appropriate car, if one does not have the cutout it will not fit an NA car. I hope this description makes sense. If more clarity is needed I'll try to elaborate.
