I have a 74 260 with an 83 L28 engine, triple phh44 mikunis, automatic and air. It's an old man's car and I have it close to running but I need to take it to a mechanic to do a little fine tuning on the mikunis. It's about a five mile trip with a tow bar. My question is: Do I have to drop the drive shaft for this distance? I'll be back with more questions later. Ravin
