Aldan Coil-overs?

[lazylongboarder]

I spoke to aldan suspensions today and they have a shock that seems to be what i want except that the spring they use is 3.25" OD. I'm not sure if that will clear everything out back of my 74' irs std beetle. The specs. I think i'm looking for are 10" compressed, 15" extended, with a 1.9" spring? They have a model (655) which is 10.2" compressed and 15.5" extended but i'm just not sure about the springs.
If anyone has any expirience with this coilover, please let me know what kind of quality Aldan is. I'm looking at their "ultimate shock" with compression, rebound and ride height settings.
Also they want $540 (pr) for the double adjustment shocks (compression, rebound, ride height) with springs which seems very reasonable. And $399 for the single adjustment coilovers (rebound, compression with preset compression valving, and ride height).
Does anyone know the prices of the Ohlins TTX44 coil overs?

Any help would be greatly appreciated.
