I’ll measure mine when I get home tonight.

"Drive Happy"Makes sense. The donor Pinto was 94.2. Thanks for the measurement. I will use this to lay out my chassis.
Received a plasma cutter for Christmas: a Locos 520D, which is also a TIG welder. I finally got to the point that I ran out of floor space, so first project it to make a welder cart that combines my old MIG, an Oxy-Acetylene and my chop saw.
First step is to lay out for welder and bottles.
Looks like a frame
With wheels
Loaded with chop saw on top
with Oxy/Acetylene setup around back. Now I can easily wheel all this in place and store it all back in place. Can start making an MG frame soon.Nice work!

"Drive Happy"The front wheels are from a shopping cart I and the rears are from Lowe’s. Both have ball bearings, so it rolls fairly easily, in spite of the weight of the stuff onboard. I estimate it to be close to 400 lbs total.
Progress. I spent all day getting the front square to the plywood frame platform and then getting the angles right for the front frame risers. Tomorrow I’ll use some pocket screws to hold these parts together.
Next I need to work on the rear arch.
I can’t tell from the photos as to what rear you’re running. As a note of caution, the popular 6-3/4″ ring gear used in the Pinto is rather weak. Once I hotrodded my motor I started blowing those things apart. Don’t know what your plans are other than a larger engine, but please consider a beefier component for your build.

"Drive Happy"That rear is just a placeholder. It came with my parts car. Yesterday I bought a rear from a 76 Cobra II, a Ford 8″. Looks a lot beefier.
Yep, that’s the one to go with. That was used all through the sixties on real mustangs with V8’s. It’ll handle your planned V6. If the tag is still attached to the carrier bolts, the ratio should be stamped in the lower left corner. Mine was equipped with 3:40’s. When I swapped to a 5 speed I switched to 4:11’s. I still have that original carrier stored in a 5 gallon bucket of oil.

"Drive Happy"Being hopelessly forever an engineer, I came up with a method to accurately measure the gear ratio. Raise one wheel and block the other. Let both wheels turn if you have posi. Make a mark (via masking tape and magic
marker) on each of rear yoke and diff housing. Put a piece of masking
tape around the entire tire and make a start mark using a chair or
something to point to the start mark on the tire. Turn the wheel until
the drive shaft makes exactly one turn. Make a second mark on the tire
masking tape for the distance the tire traveled. Cut off the tire
masking tape exactly at the start mark. Lay the tape straight and
measure the tire circumference (whole tape) and divide by distance tire
moved (second mark). Multiply by two. That’s the ratio. Don’t multiply
if you have posi.You can simplify that by spinning the driveshaft once and seeing how many times the tire turns.

"Drive Happy"In short, that’s exactly what I said, move the driveshaft exactly one turn and measure how much less than one turn the tire moves. For example, on a 3.00 rear end the tire will move 1/3 of a revolution for a full turn of the driveshaft.
It’s been a while since I made real progress. Problem was I needed to finish the design of the rear suspension. The driver was that it had to fit and also needed to change over from the MII 40″ leaf spring to smaller coil spring setup. Also had to fit either a three or four link with panhard within the confines of the room given under the package tray. Finally settled on three link without panhard, shown later.First pic shows after-market Mustang trailing arm with coil mount and also a tubular a-arm that serves both as third link and panhard.
Next pic is a frame in pieces…
First weld…
Did you (or do you) work in a high end garage? Race team? How did you acquire such skills? Wish you were my next door neighbor.
One side of frame laid out and tacked together
Welded the two frame sides.
Bracket for Ford 8″ to hold a ball joint. This serves as the third link and makes a panhard unnecessary.
A-Arm from Speedway Race catalog, later will be bolted to a frame crossmember that I can only locate once lower trailing arms are done and pinion angle set. Long way from now….
Side view…

Although I have rebuilt several old cars and trucks, some with serious body rust problems, this is my first frame. I am lucky to have a friend down the street who likes to build cars from scratch. I’m down there about twice a week with my progress and asking advice on the next step. It was his suggestion to use an A-arm instead of a panhard.
Nice custom frame. That use of the control arm as an upper strut is really a novel approach. That should work really well with the addition of another crossmember. Beautiful.

"Drive Happy"I like the A-arm idea. Easy to source part, and the setup is not unlike what Jaguar did on the early C-Type to augment the torsion bars. Have you seen road-going hotrods with that setup?
