Modern cars do not use SLA type I suspension systems with parallelogram steering, so that comparison isn't exactly a good one. Excessive caster in this design will cause wheel shimmy at high speeds and although spec is around 2° you can achieve more than spec when aligning. Either way, I would never go past 5° on these trucks. As far as the CV suspension, stomp on the brakes or accelerate and watch the amount of fore and aft movement, it's astonishing that they let them leave the factory this way. The aftermarket replacement parts are no better so again, I wouldn't if it were mine. Tubular arms aren't too bad, You can get a set for around $450

I run about 5 degrees on mine currently without issue, but to get the modern style wheels I like I have to run 1.75 adapters. Not the end of the world but I would like to go without and get some of my turning radius back. By the time I buy a steering box and control arms I am about $1k in. CV cost Would only be any maint parts I need, and will have a Rack and much more suspension travel then my lowered front end. I think I could probably fix some of that flex if I made some Delrin bushings for it. Other then the flex do you see any issues?

Clever, are those aftermarket adapters, or your design?

This is a low budget hot rod built in the garage. Mostly old parts and rust! If I can't get it at the junk yard I make it for the most part. It is the main reason I went with the crown vic. The front end was wore out. It would take $3K to rebuild the GM steering, lower it 5 inches, and make it come anywhere close to the kind of geometry already built into the CV.  I only have $100 into the CV so far.

Good job man!

I'm from the old school too, if you don't have it, can't find it, can afford it, MAKE IT!

Learned that from my Auto shop teacher in '77.

He told of making main bearings for a 4 cylinder Ford by pouring molten babbit into the block with the crank positioned perfectly.

Only problem was that the crank was now frozen in the block.

Cure: drop block into the truck, load rocks, tires and kids if available into the bed of the truck. Put truck into 2nd gear, drag around the yard with mules until the crank freed up. Trim 'new' bearings, finish rebuild.

I never challenged the story, but it sounded feasible.

@Thompson335 Thanks for posting pictures of the adapter brackets! Can't wait to see how you connect the steering column to the rack.

Picked it up at the junkyard from a SUV

Like the build.. keep it coming!
What did you use for a backing plate for the hydroboost. I have one from a suburban/tahoe/yukon, can't remember which. Not sure it I want to put it in the V10 or K5 blazer.

Can you show and explain what parts you used to connect the CV rack to the C10 steering column?

Did you have to modify the frame or exhaust manifold?

un fortunately I can not take a good pic. the first two are what  I am using now and the steering is smooth. the third pic was an initial try that did not work well it had hard spots. you can see the angle up top is to sharp but it gives you a good pic of what you are dealing with. It may have worked with a double joint up top. the lower joint looks like a double joint but is really two joints with a really short D shaft in between.
