From what I've seen most all early chromoly rigid forks were 395 to 405. Should be easy to find a Tange, Tioga Big Fork, Spinner, Aperbic or something along those lines. I have a decent quantity of GT Bologna Lites in Black and Mirror Titanium paint finishes and I think most of these are 405 but I'll get the tape out and see if any are 395. Exotic makes a 405 in carbon and aluminum. To find 395 it's almost gotta be something from 91-92 era before front suspension was on everything.
