Model A body on Frame

I'm working on setting up the frame for my 30 Model A tudor. I have a frame here at my house, but my body is up at my father-in-laws. I want to work on the frame and get the "Z" put in the front, but i need some dimension help. I need dimensions from the front cross member to the firewall of the body, so I know where to put the Z so it is hidden in the cowl. Any pictures/ suggestions on where to Z the frame and how much would be greatly appreciated! I'm running a 8BA flatty too, so pictures of a stock A frame with flatty would help greatly! Thanks!

 

Model A frame dimensions...

 

thanks chopt top. That drawing has great dimensions! I still need a dimension to where the cowl sits on the frame. Do you know where a guy can get that?

 

Does anyone know if the dimensions of where the coupe firewall sits on the frame is the same as the tudors?

The first 1/2" bolt hole on the top of the frame after the front crossmember is where the foot of the firewall mounts. "Z"ing a frame without the body present is asking for problems if you ask me though. But, thats just me.

Thanks for the help! I'll just have to get the body drug to my place before winter sets in!

 

Before Zing anything.......motor type,radiator placement,dist.location are all factors to keeping the Z inside the firewall.You may find your body moving back on the frame to allow for these factors.Measure twice.......cut once!
Having the body on hand is good advice.
