I have a 115 cluster in my camaro and I bought a 145 a while ago...well I took the 145 apart and, I don't know why, but I felt compelled to move the needles, will they need recalibated? I mean they problaby would have needed it anyways because the fuel gauge said like 3/4 and I only have like 1/4. I HAVE NOT removed the needles, I just moved them around....and from what I hear, a swap from 115 to 145 does not require somebody to do anything special.
