Probably not the best idea. The bolt will break or break the mount on the control arm when the suspension moves. Have to have the bushings to allow the bolt to twist in the end link.
The composite links are not normally a weak link unless the car is being used for racing or serious off-road use. And as with any other material they will fatigue with age and use. A new set of composite links isn't that expensive and will likely last the rest of the life of the car.
Well, tested the connector to ground for the oil light, and it seems the bulb is bad or missing. I ran a volt meter to the connector and battery ground and saw battery voltage, so it's at least getting power. I hope like hell it's not missing, as that'd suggest some questionable ethics in it's past. Out of curiosity, where is the engine VIN on the actual engine? Are they number-matched to the car? It's definitely an ej22 engine, but just thinking if the bulb IS missing, it's possible the engine might have been switched at some point thereafter if there was an earlier oil issue that wasn't fixed.
I know some cars run the sway bar directly to the control arm or axle, and the bolts hold up. I'd just be omitting the rubber and plastic, and would use the center sleeve that runs through it. Should be easy to get that out of the rubber, drill a hole through the bar, center it, and tack in place. I think if it's torqued to the same specs as the factory piece, it should be OK. Dunno why it'd hurt the mount? The rubber doesn't decrease the overall amount of load it sees and the center sleeve is what sits on the bolt. I'll be the guinea pig and see what happens. I have an arc welder just in case. I definitely wasn't racing this nor off-roading. The rear should be able to handle this fairly well; the front will have to see.
I googled some WRX aftermarket pieces and it seems the "double balljoint" with a single bar connecting them
http://ecx.images-am...419GAF4KG7L.jpg is popular (could actually buy some Saab NG900/9-3 units, mate the threaded ends, and attach together for same effect for MUCH less than the aftermarket companies want for a Subaru piece- Here's what the Saab one looks like: http://www.rockauto....1454&cc=1423088 they have Moog pieces for $5 each, so for $11 I could fab up one side and have the same effect. I did find a rather solid looking aluminum piece: http://www.oakos.com...1/KB-017-08.JPG with minimal rubber isolating the sleeve (dunno what car it's for though) so the "bar" unit I want to make would be very similar to that. Will try the bar deal first, and if it doesn't work might try the Moogs mated together. Don't forget the sway bar can move and absorb much of the movement.
