I'm not an expert on this one but on mine I only see one bolt that goes all the way to the end of the arm and attaches to the chassis, so I don't think you will have to remove the body. Just get under your car and follow it, it is kind of hidden though. Hope these pictures help.
Thanks! Those pics do help.
The aft end is bolted to the rear upright/axle. You'll have to pull the half-shaft to get it off the car.
I would think the car would have exhibited some odd handling characteristics, the rear toe must have surely been affected.
Ok that's good to know. Yes it did when I think back on it. It seemed to turn easier on a right turn than a left turn, and the car did not want to go in a straight line by itself. If I had known about the radius arm I would have had the car shipped to me instead of driving it for 2 days and 1200 miles to get it home. I don't think the guy I bought it from knew about it; he had purchased the car in January as a fixer-upper but wound up not having the space, time or funds to do it so he sold it; didn't really drive it hardly at all.
I put in an order to Banks Europa for a radius arm; just waiting for them to confirm they have it and are shipping it.
I have the same filter arrangment on my Elan only the hole points down. I've never seen a plug on one but then they are uncommon. Most people seem to like the look of individual filters even though they pull in hot air and reduce power.
If you have any questions contact Ray (RD Engineering in PA) he will be happy to help you out and sell you the parts.
These canisters must have been originally for some other car and that hole would have been for a crankcase breather filter or something along those lines. I'll just find a rubber cap for it.
Yeah I've looked at the aftermarket filters but I'm with you; they're going to pull in hot air and look like they'd be exposed to the elements more. When I looked inside the plastic carb cover/funnel I was not impressed with the amount of "obstacles" inside to air flow; 6 tubes for the bolts to the carbs, and the inside was very rough, not smooth or finished at all. The farthest carb would have a tough time pulling air through all that compared to the one closest to the air entrance, which is also going to be pulling most of the air to begin with.
I'm now seriously considering fabricating a better design for the part that fits on the carbs, but still use the stock canister and air filter.
