great car...I am getting ready to do the exact same thing. I have a 99 Crownvic eng/trans. I have a lot of questions, we need to become close friends. I am doing this cvar for a 88 year old lady in Glen Rose,I live in Big Spring. I have not started on the eng & trans swap yet but have started getting stuff ready. What to do about the speedometer? I want to keep the orginial. Also plan on using a power rack and keeping stock colum. What rear end will best fit, hope to fin one with disc brakes. I have already rebuilt the front end, added 79T bird disc brakes,rewired entire car 12 volt w/alt,added vintage air and heat,electric wipers and antenna. Car is nice driver w/292 & auto 2-speed. What advice do you have? Have you started putting the engine in yet? Thanks my name is Ron please reply, I'll send you some pictures have a lot of them...Thanks!!
