Compiled this and posted on TTORA. Thought peeps here would like it too.

RC=Regular Cab
XC=Extra Cab
4D=4 Door
PRE=Prerunner
SRU=Srunner
VSC=Vehicle Stability Control

These Tacoma's use the same calipers:
95-04 2WD I4(2RZFE) RC
95-04 2WD I4(2RZFE) XC
95-04 2WD V6 XC

These Tacoma's use the same calipers:
99-04 2WD I4(3RZFE) RC
98-04 PRE I4(3RZFE) XC
01-04 PRE I4(3RZFE) 4D
03-04 SRU V6 XC w/o VSC
98-04 PRE V6 XC w/o VSC
01-04 PRE V6 4D w/o DSC
95-04 4WD I4(3RZFE) RC
95-97 4WD V6 RC
95-04 4WD V6 XC
01-04 4WD V6 4D

These Tacoma's use the same calipers:
03-04 SRU V6 XC w/VSC
98-04 PRE V6 XC w/VSC
01-04 PRE V6 4D w/VSC

This one uses a different one than all the rest:
95-04 4WD I4(3RZFE) XC

I put this together because there is such an issue fitting 15" wheels on a Tacoma. Of course this alone doesn't tell you much, but it may help.

More to come...

There doesn't seem to be too much interest here for this info. I'll update it when I can, but for the latest, greatest, and most-up-to-datest, go to TTORA.
