1997 TJ, 4 cylinder

Error Code 54 intermittenly on Nov 05 to summer 06, now on solid.

Problems starting jeep since summer, but only after it had been running
not long before trying to start.

Just had crankshaft sensor replaced as mechanic thought it might be the
problem despite me telling him about the 54 code, plus no one in town
had a camshaft psotion sensor handy.

Question:
Is the camshaft sensor on a 97 TJ 4 cyl replaceable without removing
the distributor. This is not clear from what I've read online (the
Cherokee 6 cyl from this era requires distributor rmoved to get to the
sensor.

Replacement seems hard to come by, napa and autozone don't have it
online or local, "rock auto" appears to have it in stock, but I'm not
up for removing the distributor and doing the rotor marking thing if I
don't have to.
