Model A frames are flat-topped between the axles. '32s have a bit of sweep, though less than it looks if you actually go and measure it. Neither is quite what would have been called surbaissé in c.1930. Hence the practice of z'ing.
Thanks for the reply. Trying to figure out if I can get a "spring over" low enough for my liking with a 1" drop crossmember, reverse eye spring, and a Model A axle thats been dropped an addional 3", without Z-ing the frame. I was at a friends house yesterday looking at his 32 frame and the sweep got me to thinking.
It sounds like that thing should be pretty low... I would mock it up first to see what its like before you Z the frame
Unless you really want to go really low, all those things should get you down a good margin. Another option would be to pie-cut the frame around the firewall to enhance the sweep up front. This seems to be a fairly common practice...
My Deuce truck has a 4" dropped axle,model A front crossmember and a reverse mono spring. HRP Original...
Another perspective...go here: http://www.wescottsauto.com/SubIndexes/Techindex.html and look over the excellent side views of frames. If you scale carefully you could potentially sketch in components to judge where spindle center would end up...
There's my answer, the HAMB comes through again! Mock it up and if its not low enough, pie cut the rails. So obvious I feel kinda stupid. Thanks for the replies. Bruce - very good info thanks for sharing.
Flat cross member....super low posie super slide spring and whatever drop axle...you can always deleaf the spring too
C the frame front and back. the frame gets in the way if you want a decent ride. It's much easier to do it when you first build it.
With a model "A" frame you can also do a Rolling Bones style front suspension like on this car to get the front low.
Thanks for posting the pics. I was really trying not to hang stuff off the bones but obviously this has been done successfully. Another thing to consider.
