Replacement Stylus History
FTR = GTR = NO LONGER AVAILABLE
FCR = GCR = NO LONGER AVAILABLE
FTE = GTE = NO LONGER AVAILABLE
FCE = GCE = NO LONGER AVAILABLE
FTE+1 = GTE+1 = MTE+1 = XTE+1 = ZTE+1 = BLACK
FCE+1 = GCE+1 = MCE+1 = XCE+1 = ZCE+1 = GREEN
F3E+ = GF3E+ = MF3E+ = XF3E+ = ZF3E+ = BLUE
F2+ = GF2+ = MF2+ = XF2+ = ZF2+ = RED
F1+ = GF1+ = MF1+ = XF1+ = ZF1+ = SILVER
N/A = G+ = M+ = X+ = Z+ = SILVER
N/A = G1+ = M1+ = X1+ = Z1+ = GOLD
N/A = G2+ = M2+ = X2+ = Z2+ = GOLD

This chart is Grado's stylus history for replacement stylus. Since your cartridge is not listed and it was a signature model I would try either the Silver or Gold replacement. The new stylus assembly will give you a new suspension system which is a part along with the stylus that does wear over time. The only other concern is if the magnet has lost strength which I doubt. As far as I know with my experience with Grado cartridges the stylus all fit the same way and you may benefit from their new cantilever design.
