I just wish I could find a Vanny around here for next to nothing, maybe then I will be able to build one.  Everything I find around here is new/full price or blown up!  Otherwise the engine costs too much to have to tear down then build back up!
You never win a race by focusing on one aspect of the race!  Motor isn't everything, but you better have a good one!  Chassis too!  But remember, a driver can take a slow machine and make it faster!  I may not have/be the best of any of these but I'm trying!

There is the SINGLE cylinder class also. Build a single. They will be a cheaper build and just as much fun.. I am building one.

How close does the bell crank get to the ground when you turn left? What if you would turn it 180 degrees and mount it with the pivot above the tie rods, like an upside down L. The end that the tie rods hook to would be pointed straight down and the end the drag link hooks to would be pointed to the right side. Then so it turns left when you turn the wheel left, just make the drag link that comes down from the steering column go on a diagonal,  (it would look like a Z from the front) just like you have to hook up the drag link with direct steering on a regular EC front axle.

i dont think the arm on the bell crank will get all that low to the ground, i could be wrong, i may look into your idea Old Goat, gonna try and get some heim ends today and start hooking everything up and go from there, that is a good idea, just have to see.....

when you weld the spindle arms back on do not do them at a perfect 45 to axle. Have them go towards the tire a bit like a 1/8 inch or 3/16 this is building ackerman into the spindles.

That OR on the bell crank make that arm like a fan put rods ends side by side not on top of one another.

Lookin' GOOD, Jerb!  Dang, it sure is short! I hope you don't have to cut a couple inches off your legs so you can fit on it!  :D

Here's the way we did the front steer on my brotherinlaws mod-x. The mower is upside down in the picture

question here guys....is moving the spindle arms towards the wheel as George mentioned doing basically the same thing as what old goat did in the picture, just trying to get a better understanding at all the options when it comes to adding ackerman......
