Need 310 suspension mount help

I have disassembled my rear suspension and overall it looks good except the right rear lower control are mount:





As the photos show the front attachment nut plate has fatigued and fractured. It looks like it has been that way for some time based on the corrosion along the fracture line. The design looks a bit frail for me but it seems to have worked on many race cars.

My question is what have people done to improve the design of the part? Have many of you found the same problem? It isn't as simple as welding on a thicker plate because the control arm would toe out. I thought about welding on some small gussets but there isn't much length to weld along. I would appreciate your help.

join the club buddy..... we are here to help..... with only a handful of A310s in uk I don't think you will receive many replies, answers can be found via the French connection.

I've had some made with thicker plate for the RATS' Racer .I have seen them fail on a GTA ,luckily the guy was just backing it out the garage,the wheel went into the arch .......
As long as you maintain the dimension from mount face to bush center then no problem with tow .There is plenty enough clearance,on GTA version ,from inner face to bush main od .6mm plate .

As an A310 owner the only comment I can add is that my Phase 1 differs from the Dallarax Phase 2 car. On my car the brackets are welded directly to the chassis rails, not bolted as on the Phase 2 car. Toe in/out is set by an adjustable link attached between the top wishbone chassis bolt and the rear hub.
The photos are maybe too small but the first photo shows the two brackets welded to the chassis. The other photo shows the toe in/out link (with the rubber cover over the outer end ball joint).

Thanks for the reply! The French guys recommended an R5 Turbo part

It still seems fragile for my liking. The alternative is to relocate the rear pickup hole outboard and build a thicker front bracket. Or change the rear triangle http://3sdeveloppement.com/triangles/14 ... paire.html
also recommended by the French guys. I have a bit of time to contemplate the options.
