Forgot to mention that I am using FF 1.00" torsion bars with a 200 lb/inch wheel rate. I am happy with these, but I think they are definitely stiff enough for my taste. Part of that is that I am running P245/40R-18 tires on the from of my Coronet, so they are a lot stiffer than the stock tires...

I just wanted to add a quick clarification here regarding the difference between "Spring Rate" and "Wheel Rate". In general, the value of interest is the wheel rate, as this is how much force is generated by the spring (regardless of type) for each inch the wheel is raised. The spring rate is...

This may not apply to your situation, but I thought I would mention it anyway. There is at least two different "blue" Loctites. The usual one is number 242. For cars, I recommend 243 which has similar specs to 242, but is listed as being "oil resistant". It will cure better if there is a...

You could also pick up a pair of Firm Feel's leaf spring hangers. They are set up with holes for stock ride height or 1.5" dropped ride height. I used them to drop the rear of my Coronet. Cheers!

Thanks for the offer, but I'll pass. I'm busy figuring out how to replace the wiring in my car at the moment. That's occupying pretty much all of my time currently. I don't expect I will get around to changing the torsion bars again. Hope your friend is having fun with his car. Cheers!

This is a complicated subject. The first thing to decide is what he wants to do with the car. If he wants straight line acceleration, that's a different setup than for cornering. I don't know much about straight line setup, so I won't discuss it. For cornering, the tires are the key factor...

This sounds like a very similar project to my current one. I am completely replacing the factory wiring in my Coronet. I too am mostly using Deutsch connectors (the Amphenol versions are cheaper here and intermate with the Deutsch versions) as I don't like the Packard connectors originally...

There shouldn't be any risk with a stock alternator, as the system is designed so that the stock alternator cannot source enough current to cause problems with the stock wiring. The issue you are referencing is only a concern if the stock alternator is replaced with a higher output unit without...

I just wanted to add my agreement with this point. If your alternator can produce a lot of current and your battery is dead, then you could easily overload the stock wiring through the bulkhead and ammeter even if you haven't added any loads to the system. A dead battery will draw quite a bit...

Hi there. Looks like you have a fun build in front of you. The 8.25" differential may be stock for that car. I have one in my car that I am pretty sure is original to the car. I did some investigating and it looks like they did use the 8.25" in some Coronets in 1969. If you find the cover...

My 69 Coronet 500 has an 8 1/4. It is a 318 car. Cheers!

Just wanted to throw in my experience. I have the Firm Feel upper control arms and have been happy with them. I have Torque Thrust II front wheels, 18" diameter and 9" wide, with 0 mm offset and have had no clearance issues. When I first assembled the new front suspension, I did my own front...

You can buy at least some Packard 58 terminals through Mouser Electronics. Note that Packard 58 is only for the female terminals, the male terminals were never updated and Packard 56 male were still used. Mouser lists the female terminals as Aptiv (formerly Delphi, which I think was the...

Yes, polyurethane bushings are built the same as any conventional bushing like brass and such. The shaft rotates inside the bushing, making it a sliding joint, which requires lubrication, you can get lower control arm shafts with a grease fitting if you don't already have them. One other thing...

This shouldn't be necessary with poly bushings as they are a sliding joint, whereas the rubber bushings are bonded to the inner and outer sleeves and set to their relaxed position when the car sits at its normal ride height, so suspension movement causes the rubber to stretch when the car sits...
