I'm getting the factory tranny cooler, even though it won't work with the rhino grille... I'm hoping the steering stabilizer setup can be made to work. and I'm going to get the wiper arms and maybe the entire motor setup. need to pickup some WVO and stuff at Lowes on the way... will be the second run with better seats and fuel lines... have had a couple folks look at the Rav4 so far... hopefully it'll go away soon. BTW, wagoneers.com is coming up for renewal again... any of you jeep fanatics win the lotto so you can buy the domain? :) john ------------------------------ Date: Sat, 25 Jun 2011 22:29:22 -0700 From: Jim Blair Subject: fsj: O/T Any Datsun guys around? The '84 Datsun 720 2wd king cab with Z24 motor and 5 speed I'm about to part out is at my cabin 50 miles away right now so I can't see it. Trying to recall if the motor is front, center or rear sump oil pan. I found a '78 B210 fastback needing a motor and I was thinking the Z24 and 5 speed would be a good swap in (I did it years ago when I was just starting out as a wrench with an L18 and 4 speed with 510 wagon diff) I tried the forums, but they seem to be dead.

Lynnwood, WA. The intersections there had a lot of people running the red lights (probably because our lights aren't syncronized and some take a long time...) We've seen 4, 5 cars just go right through... so, there was a good reason to install them... however, it seems that the time that the yellow light is displayed is shorter than it used to be. I can't find any specific laws in the RCW for Washington state to state the minimum time required. I found one reference that there was a standard of 3.6 seconds minimum for a 35 mph zone. Well, the reason I bring this point up is that my wife got the picture of our car taken... she's driven this same intersection for about 25 years... is a very safe driver with nearly 40 years of ticketless driving. She said she was coming into the intersection to turn right and was slowing down to turn and the light went red quickly... snapping her picture. She said she would have had to slam on the brakes to stop in time... I may go to this intersection (it's by the barnes and noble on 196th/alderwood mall way) and time the yellow lights... my wife doesn't make stuff up and reading through a number of complaints on the web it may be that the city of lynnwood has tweaked the lights a bit in their favor. I don't part easily with $124. Anyone in WA know the RCW for traffic light time requirements? found an article that legislation is to be introduced about it.... http://www.king5.com/news/politics/Lawmaker-wants-to-regulate-yellow-light-times-114742269.html any suggestions or ideas are apprecited... in other news, I managed to get a few more things fixed on my '83 J10 (#27)... steering stabilizer, wiper arms, connectors on the coil... saw a really ugly dog today as well: (pictures of FSJ included) http://fotomeister.us/2011/06-Jun-25-rainbow-yard-BoHenry-FSJparts/ALL.html john ----- - ------------------------------------------------------------------------ -o|||||o- Snohomish, Washington - where Jeeps don't rust, they mold http://AMSOIL.com/redirect.cgi?zo=283461 http://JohnMeister.com HTTP://WAGONEERS.COM http://fotomeister.us - ------------------------------------------------------------------------ ------------------------------ Date: Sun, 26 Jun 2011 08:01:24 -0700 From: Jim Blair Subject: fsj: RE: 1968 Jeep Wagoneer, 55,000 on original Kaiser motor, for sale in TX Wrong list but I'll pass it on to the FSJ list for you. 1968 Jeep Wagoneer, 55,000 on original Kaiser motor, for sale in TX Posted by: "patricia_dougherty" purrfectharmonyfarm-at-wifi45.com patricia_dougherty Date: Sat Jun 25, 2011 10:13 am ((PDT)) I have a white/red interior 1968 Jeep Wagoneer for sale near Dallas,TX.

Yes John, big tires would do it, but I'll leave it as it is by now, I plan to use it very little in the city for the next year, it'll mostly be in the garage. In my country there are very few of them, I live in the main city Montevideo) and I haven't seen another one in years. So... there are no spare parts of a 46 year old truck. I bought it because I have always been in love the model, the lines, the front, and I paid 5000 US dollars for it, the same value of my 92 Chevrolet Chevette, I ran out of cash, ja ja.

In 1974 Jeep began using an open knuckle front axle. This means that the u-joints at the axles are visible and more easily serviced. In addition, a tighter turning radius is possible. Closed knuckle axles are more involved to service. There are likely other pros/cons that others can discuss. *** john at http://wagoneers.com *** - -----Original Message----- From: Ernesto Silva Date: Sun, 26 Jun 2011 12:34:56 To: john Cc: full size jeep list Subject: Re: fsj: Re: original tire size - 1963, conversion table???
