I have a guy that might want to trade a 87 Bronco 4.9 with a manual tranny for my 87 E-250 van. His bronco has 97,000 miles on it. He said something about the timing gears needing to be replaced. He has the parts and is going to do that. He listed it for $1500 or trade for a cargo van. I will happily trade my van for it if he will take care of smog on the van. What manual tranny should I expect to see in that? Also, he figures the A/C will have a leak and need a recharge. How much does that normally run?
