Suspension dilemma

[DocDirk]

Hello Norcal folks! I'm coming close to almost kind of nearing the part where I might someday soon .....oh well, I guess it'll never actually be FINISHED, but driveable...I hope so!! Anyhow I posted a question on the All Cobra Forum about my suspension and haven't yet figured out if I have a problem. The rear control arm is attached to the chassis at a point which includes a horizontal top, this limiting vertical motion. I include here a photo of the left rear assembly with the car on three wheels, the frame on a jack on the left rear. The rectangular control arm is at its upper range of travel even without a load on the car such as passengers or a bump in the road I cannot get a response from the manufacturer so I'm hoping someone might be familiar with an answer to this query or perhaps steer me to a good build shop in N. Calif. where I might get a professional answer if it's not obvious from just looking at it. I'm tempted to cut the top out of the attachment point to give the arm more vertical travel but I'm not a pro and assume the folks who built this chassis did that for a good reason....

Thanks for any replies and I hope to see y'all some day soon!
