I guess having an older truck has it's good points, to recal on the '95 there's a wire under the glove box that you short to ground and then using the select and reset buttons on the dash you set the speedo for the size tire. Only problems is you can only do it 5 times so you'd better be right.

Supercrewz was it Allan Vigil in Fayetteville or McDonough?
