Re: [AMC-list] Truck arms

[Frank Swygert <farna@xxxxxxx>]

51" should be sufficient. I don't think I'd go shorter for a street car. 
I had to look up the monoball thing, looks good.
Wouldn't be hard to make a crossmember from scratch -- you've got the 
tools and knowledge to pull it off.

As far as moving without the TT installed, what I did was take the TT 
and strut rods off an axle then screwed a 5' or so length of 2x4 to the 
pads (stood on edge, 1/4" lag bolts or drill through) the shock/strut 
rod mount was on (took all that off too). I thin nailed a piece across 
both ends on top to keep them straight, and let the car down on the wood 
frame. A couple screws through the floor kept it from coming out when 
moving around. All I did was roll it around the yard like that, hitting 
anything that would really stop a tire might be a problem with just a 
couple screws (literally two!) holding it in. The small holes in the 
floor would be easily fixed, though mine was a parts car. Put a few more 
screws in if putting up on a trailer!

Frank, think these will work?

They have the mono ball ends, so I may have to swap those at some point.
I plan on going with them as a monoball setup is about $30 to replace 
the missing one.
The Arca and the Nascar arms are the lightened versions now selling for 
big bucks
on stockcar parts.com.

I have been watching arms now and again and I am not certain what 
possessed the
seller to lower the price on what was already a good buy it now.

They actually make and sell 45 or 46" arms now. It appears that some use 
the short arm
on one side and the long on the other. I believe this pivots the rear 
axle ever so slightly
on the circle tracks and helps cornering.

Yeah, I am onto the crossmembers too.
Hotrodstohell and I believe Classicone (something close to that name) 
anyway.
They both sell prefabbed crossmembers. I expect that once I get some 
dimensions on
the Ambassadors frame width I will call and figure out which crossmember 
to go with.

I hope to mock up the lay out with the existing rear.
I think I can pull it off with removing the angle braces and torque 
tube. But I need
to figure out an antiroll means to keep the axle from rolling once the 
tube and braces are gone.
Propably tack weld in some braces. Then bolt on the Truck arms to the 
housing and lay out
the crossmember placement.

Once the cross member is laid out and in it should be a pretty 
straightforward swap to an open driveline axle.
Still pondering what that may be.
Once I get an accurate idea of axle width I will probably hit the one
pathetic pick ur own part yard we have here.

I wish I had the floor pan from my parts car to flip and work from.
But I hacked the floors out of it a long time ago, so that option was
long gone before I sent it to the scrapyard.
