Hi All
I just finished installing a set of Peter's torsion bars and Manny's one ton front end as my old bars we're adjust to the max and the front end was about one inch low. After the install I guessed about where to set the adjusting bolt I set it about half way and now the front end is an inch and a half high. I have driven it like this about 30 miles and if it stops raing will go out ant lower it

I agree with that prescription. When I got back from my 4 mo. trip out
west last summer, all the doctors who'd been feeling abandoned in my
absence were waiting to see me. They were all shocked: My lab results
were all the best I've produced in years, and I'd lost 7 pounds. Quite a
surprise considering the way all the folks, like Jim & Judy, fed us along
the way; and, the way I pampered myself as much as possible. :-)

When you say you are going to add to the hex does that mean that the overall length is still the same just the hex area is longer to take advantage of the beefed up area going into the a-arm. I've been driving for 2 years now with spacers in front of the t-bars and the crossmember moved with the T-bars sitting in the beefed up area, back after I slipped a t-bar in the left a-arm, no signs of a problem supporting in that area. Since we are talking t-bars is it normal for them to show a bow or is that a sign the bar is loosing it's strength and I should take advantage of this second chance to get better bars. If I was to put in the upgraded T-bars I guess I could pull out the adjustable porkchops and put the stock back in? Thanks for any inputs.

The purpose of the extended hex is to engage more fully, the socket in the
lower control arm. It is a weak point that is often times reinforced when
the control arms are rebuilt. As some of you have noted, there have been
occasions where they have cracked and broken, allowing the torsion bar to
rotate. Not a good thing to have happen at freeway speed. Overall torsion
bar length is the same. When the manufacturer forges the hex on the end, he
merely makes it a bit longer. Peter feels, as I do, and as Ken Henderson
recommends, that this is a good modification to make.

Skip, no it is not normal for them to be bowed. But I have seen several
that were. Ron Smith's were badly bowed as well as twisted enough that no
stock pork chop could get the coach to ride height. As these things age out
we should see more of this.

Are the torsion bars a go? I would like to sign up for a set if it is not too late.
