Is the vinyl something that could be used to covered a worn and cracked dashboard? Some that is smooth

Very pretty for sure but Pete it is not a natural lake. Relatively recently created, 1963, to generate electricity. Not to be confused with Mountain Lake, also in Virginia, which was the setting for the film Dirty Dancing

The inside looks pristine. What was the odometer showing?

IDMJ, the floor does look surprisingly good. There must not have been leaks around the windshield. The screws and rubber and metal plate look new. Was a round boot the original shape? Think a po had changed that?

dasbulli, would you mind checking my vins? Do you have where the were sold new? Thanks in advance! 87 4.0 5 speed 1JTMW641HT179206 89 4.0 5 speed 1J7FT36L4KL436210

Myles, what was the final solution?

Now Gene, don't make these guys so swell headed they won't answer questions from an ignoramous like me.

Mean Leoms, tell us about your kit. Gotta link to it?

My best measurement indicates the 4.75" alernator. I looked for a plate but could not see any from above. Totally not visible from below. Put my phone down by back and below. I see no markings for part number or amps. I am surprised a 4.0 would have the smaller alternator. The deatails on driver door are totally blurred. I think it started life as a Pioneer but don't really know

Powermaster is a rebuilt one?

So the 3 gurus are dealing with this. So a Delco alternator does OR does not need a voltage regulator? I am seeing conflicting answers here and in earlier threads. I am not looking for the cheapest way out of this. I AM looking for a solution that will be the most trouble free AND the easiest for someone to figure out 10 years from now when it might need replacing and no ones remembers a nonstandard installation. Not clear about which wires need up sizing. If a Delco does not need a voltage regulator and it was so dependable that thousands were made, wouldn't that option make the most sense? 89MJ 4.0 going from no ac to factory style ac. And a new twist: probably will go from manual windows to 97 doors with electrical windows; don't know if that matters

That is a lot to know. What are the chances that the alternator on an 89MJ 4.0 was the same size if ac had been there to begin with? How would I find amp output without and with ac for an 89 MJ4.0?

Hornbrod, i was thinking you were probably a nice guy up until now. That was scary thread. It appears you knew what you were talking about 10 years ago. I am not on fb (don't want to be) so could not see that last link. Long story short, you think alternator with more output will require some rewirimg and fuse panel? You think the Renix era had separate voltage regulators?

I am going to have ac put in 89MJ that never had ac. I am not doing it myself. I will use same mechanic that just replaced all ac in an 87MJ that did have it. I asked him if i will need to replace alternator with larger one and battery also. He said he would check ratings. Reasonable. I asked if voltage regulators were still separate back then. He did not recall but would check. Decades ago, regulators were replaced at time alternators were. A bad regulator could burn up a new alternator. My understanding is that at some point regulators were built into alternators. Today the function is done by on board computer. My questions: was regulator still separate on MJs or built in? Other than alternator and regulator, will any other changes be needed? I don't want to burn anything up which mechanic said could happen to undersized alternator.

You guys are good. Hope i am not up to quota. Will ask your expertise for possible need for electrical upgrade shortly. Diff thread

Called scuff plates. Learned something

Duh. Yes. They are plastic on the 89. I am not near the 87. Are those plastic also? Hopefully can buy new ones?

I am asking about the thin aluminum? plate that covers the edge if the carpet and goes under the door. Not part of the frame

There is a piece of metal - horizontal - below doors that I think is called a door sill. Does anyone know if new ones are available?

Hornbrod, how do you happen to know all that? Where should I be looking?

Settled today. $1,998.01

Hornbrod asked? How's it running? Does VA have emissions testing? It runs fine. I have had the 89MJ for 2 years. Purchased with 57K miles on it. Now 75K miles. Only northern Virginia test for emissions control. I am in Virginia Beach; eastern/southern corner of the state. After reading the posts here, i googled and found all said that it could not be reset but could be replaced. One person said that replacement would cost about $45 and be good for another run of 80K or whatever it was intended to run. After your comment I think I will replace the O2 sensor and the pcv which other sites indicated is what the light intended.

What did you chose to do? Does anything need to be done or replaced with O2 sensor?

Emiss Maint light came on. 89 MJ. I see multiple threads that are old and some closed. Some state that the light comes on based on reaching 80,000 miles. I just past 75,000. Some speak of O2 sensor. Some state it is does not really know if the O2 sensor is bad or not. Other threats state that some O2 recalls are still open and free. Would someone pull all of this together? How do i turn off the light?

Cruiser54, good luck with your 98 Grand Cherokee. I bought a 95 new and drove it for 357,000 miles. Engine still rolling along but when the tranny went bang for the third time, I did not go forward with it. Still have it but just parked. Engine, ac, other all fine. Who knows maybe in 10 years they might become a vehicle of interest. Was so many on the road though. I still think the side view of that Grand Cherokee back then was a home run for Jeep. I called Jeep about it hoping they might want to buy it to tear apart the engine for evaluation. (GM has done that) but all they did was send me a license plate frame that has "Jeep" at the top and "300,000 mile club across the bottom.
