I started working on the model A yesterday. I chopped it 3 inches and channeled it 3.5 inches. I stared looking at the old frame I am reusing that has a 12 inch kickup in the back, but with the model A box on the frame the back of the box is just below the the rear window. Looks goofy so I want the box lower, but the frame is too wide by a few inches to channel the box over the frame.
So the question is, should I narrow the frame behind the cab or reduce the kickup? I am planning on running Quarter Ellipses in the back for suspension. Any pics of model A trucks and how much kickup they have would help.
I am going for a low suicide front end 5" off the ground in the front and back. Any help would be appreciated...

I kicked up my one 6 inches in the rear and 4 inches in the front. Put a three inch dropped axle in it too

4eva Any pics?
do you have any pix of how it looks with the bed below the rear window?
some times with the right rolling stock it can work.
just trying to get a visual

Tim I will take pics and post tonite. There is no suspension on the back, but I have it mocked up.

I'd be tempted to make a new back half of the frame.
If your going to reduce the amount of kick up,you can pie cut the rails,from the inside,right behind the cab and pull the rails in at the back.Then you can drop the box down.
Check out the chassis build here: The Antidote. (http://www.the-antidote.com/frames/1home.htm) It might give you some ideas.

WOW!!!!!!!!!! http://www.jalopyjournal.com/ubbthreads/images/graemlins/shocked.gif That is a great site... I like the idea of the pie cute to tapper the rear of the frame. Thanks Unkl...

I've got a 12" kick up on my A PU and the bed Channeled over it so that the tops of the rails are about 4" below the top of the bed. I made my frame out of 2x4 rec tubing so it was narrow enough to slide the bed over the top. I also channeled the cab 5" over the rails. I'd do what was mentioned above and fab my own rear clip.
I'm also running a spring behind suicide setup in the front with a 4" dropped axle. LOW is the theme for the day. Had to mount the motor high in the frame so that I had 4" of clearance under the oil pan. I'm building a 28-29 style following the lines of a model that I saw. Here are some pics in progress and the last two are of the model that inspired it all.

This is my 33 ford....cab channeled 5" over the frame and the skinny model T box sits on top of the original, factory 5.5" kickup. I rather like the look of the box just below the back window.

Rocky raises a good point.
It is possible to have the box too high,or too low.
Consider the top of the box,and how it relates to the belt lines of the cab
and the bottom of the side windows.

Ya I am trying to get the box sides just below the Beltline in the back. Much like the Rocky33. So I am looking to drop it about 4-5 inches. I think that I might need to redo the backend. I like the pics and the specs on the channel and the amount of kickup.

I'm running about a 13" kick,4" channel, rails about 5-6" off the deck and built my frame along the lines of that antidote site,Ill be channeling the box over the frame quite a bit, the top of the A crossmember should be about level with the top of the box! The frame will sit through the box about halfway around the curve in the bed bottom( I hope...havent got the bed yet)
I reckon narrowing the rear of the frame will be your best direction.
if your using quarter elliptics i guess your kickup wont be as much.

Hey Rocky-
How much of the bottom of the box was left on your truck. Was it just the box or was the "skirt" that is below the box still on. Hard to tell from the picture kind of dark in that area.

Not really sure what you're axing me so I'll just post another [not as flattering] view..hope this helps and if not, let me know...

Thats all there is to a "T" box.I would say that if you want it low you should narrow the rails just enough to lower the box over it.
My frame has about a 12 inch kickup, the body is channeled about 7 inches(I am gonna raise it about 3 inches though)...Here is a pic

Thanks Rocky that answers my question. Sorry to have to make you post a not as flattering (but still cool)pick of your legendary 33.

Looks good Haas...Do you have any pictures of the back with the tailgate gone to see the frame. And how much is that chopped...

9 1/4" step up:
here's what we did for my 30 pickup-
4" dropped A Axle
reverse eye front spring(original spring with 4 leaves removed)
600's on the front, 750's on the back..all tires mounted to 16x4 wheels-
ford 9" rear, with a T spring mounted behind the axle-
mock up engine and trans in place(56-324 & sag 4 speed)-
we set the frame up at the stance that i wanted(1 inch higher in the back)
this was done with jack stands in the rear to get the angle we were after..the front was sitting on the tires.(with weight of engine )
because the spring in now behind the rear axle the frame was stretched and notched to get the wheelbase back to where it belonged(103 1/2 "), this was created by using 2x3x 1/8 rectangular tubing-and stacking that on the frame and cross member creating the notch, than pie cutting the inside of the frame rails just before the notch to maintain the proper width of the frame. after the wheel base was set a measurement was taken from the ground to the inside center of the rear cross member. next the rear was set on jack stands, with the tires and wheels i will be using(750x16), and the T spring on the rear- put an angle gauge on the rear spring bracket, setting the rear up to be sitting at 0˚. Another measurement was taken from the ground to the top of the T spring(with a few leaves removed). now we subtracted the two measurements from each other the difference was 5 1/4 inches, i made the step out of 2x4x1/8 rectangular tubing, i braced the hell out of the rear of the frame, cut the tack welds that were holding the notch in place and tacked in the step-
total step is 9 1/4 (5 1/4"+ 4" tube used to stretch frame)-
there is still wiggle room to get the stance correct by adding some leaves to the rear spring.th rear was than installed on the frame, and the frame is officially a (tacked together) rolling chasis!
ladder bars are all tacked in as is the trans cross member
i took a shit load of the whole process.....i'll try to get them up soon-
