Hotchkis TVS and ECE Rear crossmember/trailing arms

[chevyguy_72]

Ok here is the situation.
I need some people that have the TVS kit installed to chime in please.
I am looking to order the full TVS kit for my 72. Would also like to upgrade the rear crossmember and trailing arms with the Early Classic pieces.
I have talked to both Hotchkis and ECE and we think they should work together.

The hotchkis kit comes with the blade style rear sway bar that require you to drill and weld a plate to the stock trailing arms. I am thinking of having ECE drill the hole and weld a sleeve in there for the bolt to go through so it all powder coated and ready to go...

The question is... could someone that has installed the Hotchkis kit measure exactly where this hole goes? Either from the middle of the coil spring mount hole OR from the middle of the trailing arm mount bushing hole?

I have called Hotchkis they cant give me the number I am looking for. They did offer to call some customers with the kit installed and see if they could get an answer for me... I thought I would do the same here and then we could compare notes...

I am hoping multiple people chime in and we are close on this measurement.

So... Sorry for the novel but any repies are greatly appreciated...
