Well a bit of a set back as far as time goes but a better car because of it (I hope). Took the time to rework the lower a-arm mount to fix the bent one. Decided to go for the adjustable idea. As a note this only worked because I decided not to weld the stiffeners on when I fixed the frame. They need to move with the a-arm mount shaft for this to work. Anyway A bit of cutting and grinding and welding to get a cam system to work. I should be able to get up to 5 Deg caster with my new system but I will let you know where I let it sit when I get time to do the alignment on the front. Anyway the fun part:
Before:
You can see the right side mount doesn't even look even to the left side one. Can't believe I didn't even check it when i was fixing the frame. And then I gusseted it in there too. The string line was my center of chassis measuring line. Be cautious, because the engine sits off center there are many illusions that make the string look off center as well.
I started with the bent side and left the other side untouched for reference measuring. cut off stock mount:
I designed the plates and cams and had them plasma cut at my work. Tack in the main plate using the stiffener as a hole spacing guide and measuring to the stock hole position:
Close up of some gobby welds. Not pretty but I know there is penetration:
The gussets are spaced to fit the cam so it can push off the gussets as it turns.
After both sides are welded:
Paint (not POR15 but oh well) and assembly:
Be interesting to see how well this paint holds up compared to the POR15. I am planning to touch up with the chassis coat so it will get that as well.
Not real clear but close up of the cam system:
The square hole is made to accept a 3/8" ratchet (with extension) for adjusting the cam. Had to put it on top so future adjustments will be a bit tricky but it was the only way I could figure out how to do it.
Oh ya had to slot the other end bolt hole to allow the movement. Only about 3/32" so not worried about structure.
This gives me about 1/2" movement from stock location at the rear 9/16" bolt (cam). At the ball joint I get about 15/16" forward movement from stock and 5/16" outward movement from stock. The outward movement can be adjusted for by the top shims to correct the camber.
Once again I cannot say this worked until I do the alignment but I am confident it will. I will post the alignment specs when I finish it.
