The 145a has a phisically larger case than the 105a but they mount the same. The 145a is a plug and play upgrade for the 105a. I just did this to my truck when my 105 died. The problem I had was waking my damn instrument cluster up. I had to start the engine with the alternator unplugged, then plug in the alternator and start it charging after the engine was running for a few moments.
2004 CCSB LB7. EGR system is MIA. DSP5 is now gone, turbos cost too much.
