The '73 seems to be kind of a hybrid. I've got a '73 non-tilt column that I'd part with but I'm not sure it's close enough to what you want to be worthwhile. It's in eastern WA. I believe '74 was the first year of the newer-design columns that were used through at least '78 -- that's about where my experience runs out. If that's right then Chevy/Saginaw parts might be a good possiblity. Chevy columns of similar vintage probably wouldn't be too hard to swap in. My neighbor has a '70's Camaro column in his '66 Mercury pickup. I measured it once and figured it was almost a bolt-in for my '71 if I ever got that bad off. It should be even easier in a '74 or later FSJ. If you can't make cheap Chevy parts work for the turn signal, I'd get the one from Napa. The piece from the HELP section will be alot of trouble to make work, if it's the same one I've seen. Assuming the profile is a good match to the original, you'd have to drill out the rivets on the old one and then rivet the new one in it's place. Used turn signal switches are a good idea but it didn't work well for me. I swapped in a couple and then finally broke down and paid $75 for an NOS one from a Jeep dealer. Fishing the wires through the column is a pain and not worthwhile if the used one only lasts a few weeks.

After happily running BFG All-terrains and Mud-terrains for years,and after reading all the rave reviews about the MTR's, a couple years ago I thought I'd give them a try. Although I haven't had the chance to off-road them as much as I'd like, I've been very happy with them both on and off-road, and they don't seem to be wearing any faster than my BFG's. I'd buy them again,although there are some other really nice tires available these day's as well. Another nice thing about the MTR's is the extra insurance afforded by their sidewall compound. One of the hardcore(little Jeep) rockcrawlers in my club is only holing sidewalls in the MTR's on an occasional basis,whereas when he ran the BFG's it was a regular trip to the tire store for his warranty certificate replacements.

Wednesday I bought a set of Goodyear Wrangler MTR's and put em on the '89 GW. These are some beautiful Mud Tires. I am happy to say that these tires are great for the daily driver as well. They are pretty low noise and are doing great in the snow/ice/slushy conditions here in Vermont. I haven't been on any trails with them yet, but they got great off-road reviews. Does anybody else run these on their FSJ? Have they seen any trail action?

Ahhh... from the intake manifold, under the carborator. Simply, when the pistons go down in the gas intake stroke (#1 of the 4 strokes), they are pulling air through the carb, through the manifold and into the piston. If the throttle is closed (or partially closed), the throttle butterfly obstructs some of the air and a low pressure area is formed in the intake manifold. The low pressure area is vacuum. There are differing degrees of vacuum. Wide open throttle -at- low RPM(little resistance through the butterflies) being the lowest vacuum. High RPM engine, with the throttle closed (as when coasting going down hill, or engine braking) being the most vacuum. Idle and normal driving are somewhere in the middle. Vacuum lines originate from the intake manifold. At least unregulated vacuum sources. (is that manifold vacuum?) Regulated vacuum comes from somewhere else. Being an EE I would say that the vacuum canister (acting as a capicitor) with a small tube (acting as a resistor) sourced at the intake manifold would provide an RC timeconstant on the vacuum level. (is this ported vacuum?) Or does the carb do something to regulate the vacuum? I guess a one way valve would help, too... There are uses for each. The cruise, heat flapper controls (on non-cable driven flappers), TC switches and other things requiring more or less full time vacuum use the regulated vacuum. Timing advance uses unregulated vacuum. This is just a brief intro into vacuum. Anyone care to elaborate? Greg fsj-less in MN. . Yahoo! Mail Plus - Powerful. Affordable.
