Although it's a universal fit, a true parallel flow condenser is the most efficient for 134:

are the parallel flows still good for R12???
I ended up shit canning the Spectra condenser I got from Rock Auto, going with an AC Delco one from Highway Stars instead. Seemed sort of flimsy to me and didn't like the way it fit.
those AC delco replacements are upgrades from stock correct? or are they exactly the same? the pic of it on their site looks like the tubes aren't as big or something.
