The silent block bushings have an inner and outer steel shell, with rubber between.

Agree with threepiece. I suggest you drive out the rubber center however you can - drill, whatever. Then take...

FYI - it is very difficult to diagnose and fix electrical issues without the car in front of you. Sorry, I have no personal experience with such a late-model Jeep. All I can do is tell you the...

Apparently the pre-80 manifolds are pretty good, and the '80-up log manifold for the driver's side is not. The passenger side does not change. Might be worthwhile to explore how to run the earlier...

Right, why? Use the axles you want with the right wheels. Both fronts are Dana 44s, so you could maybe swap knuckles between them. Nothing like that for the Dana 60. AFAIK there is no straightforward...

Wow, 2012. Good thread, and worthwhile to bring it to the top again.

My '82 has the battery symbol for this gauge, which applies to either an ammeter or voltmeter. No need for any additional...

You've got it backwards. Closed is on, open is off.

If you lose the ground to the dash, the CVR will go closed, ie constant over-voltage to the gauges. This is bad.

The IC conversion (7805 or...

Ooh. Pushes all my buttons. The 4-door Cherokee was the down-market version of the Wagoneer from 1977 on IIRC. A manual transmission (T-15 or T-18) and the 258 is a nice combo - no need to replace it...

'77 is Motorcraft, according to my books. And a mechanical (!) regulator. Probably more reliable than Motorola, but still not in the same league as the unitized Delcos.

The Motorolas have rectifier...

Don't know for sure, but that seems right. The tail lights change too, from disks with the early beds to tall and thin with the later beds. I'd guess the disk tail lights (which are the same lens as...

What pulses? The gauge readings? The headlights?

If the truck runs, I would leave the ignition alone for now. First make everything work like it's supposed to, then start modifying.

The 258 radiator is a different size from the V8 radiators, and may be hard to find. The core support only fits the six cylinder size radiator.

When I repaired the radiator in my J10, I took it to...

If it bounced randomly, it might be a loose wire.

If it acts like it on a timer, (roughly) a second high, a second low, repeat, it's got to be the load of the CVR pulling the meter down.

Also,...

The 7805 mod only affects the oil, fuel and temp gauges. An '85 should have an ammeter, not a voltmeter. Read about the ammeter bypass in a sticky thread at the top of the tech forum.

Looks good!...

No apostrophes! The single quote on the PC seems ok, but the apostrophe on your phone (?) wreaks havoc.
