Adjustable Strut Rods

Ok, the website had gotten better.

What I have is M&H 12.5/28-15 bias ply cheater slicks. What I want up front is a 4.5/27-15 front runner. The web site says that’s bias ply too.

How much better this stuff is now than it was 40 or more years ago is hard to say but I’d think it would be at least somewhat better.

They probably are better than they were back then. But with that narrow of a tire up front I don't think it'll make a lick of difference. You don't need to run much positive caster with a bias ply as some of that "self centering" response comes from the tire construction itself, radials want/need more positive caster. Part of the reasoning behind the factory alignment specs was also the factory designing in understeer and tailoring the alignment to the "little old lady" that didn't want any steering effort. That whole 70's no feedback steering and floaty ride quality was as much a part of the design consideration as the bias ply construction was, the slightly negative caster was part of making manual steering cars feel like the super over boosted power steering cars.

So, as I said earlier, if you're running bias ply's because you've got cheater slicks for drag racing, you might as well align it for drag racing. Running 0° camber won't hurt anything if you have bias-ply tires up front, and those front runners are so skinny negative camber wouldn't dramatically improve cornering anyway. All it would do is add more rolling resistance which you don't want on a drag car. I wouldn't run negative caster regardless, but with bias-ply's you don't need much positive caster either so if you ran a degree or so positive it would be fine.
