Reply to "How fast am I going?"

I've found that unless you run a 26-1/2" to 26-3/4" dia tire, the speedo will always be optimistic. If you measure your particular tire diameter, then it's a simple ratio of 26-1/2 divided by whatever the skin is on your car, to find what speed it should be showing. Note- a 345-40 Goodyear will almost never not be the same dia or width as a 345-40 BFG, MIchelin or whatever; you MUST measure what you have, on your wheel. A type 1 gearbox originally had a very low ratio ring & pinion; most were recalled by Ford. Some have since been modified. Type 1's have a bellhousing with two small access ports centered in the top edge, the type 2 has a single larger port in the left side. The gearboxes & bellhousings do NOT interchange- its a package deal.
