1969 Camaro with TCI Rear torque arm having issues installing DSE minitubs

[DX11]

I bought this car with the TCI suspension already on,

and And I bought DSE minitubs
but my metal guy is having troubles installing

I was told there is 2 different torque arms
one for mini tubs and other for not ,
If it’s not the minitub one what can I do? Does TCI sell a conversion? Thanks

It would probably be easier to call TCI, and get info straight from them, i have the TCI non tub setup and the wheel tub mounting brackets are different for the mini tubs , but the torque arm is the same, Call them to make sure info is correct, they are very willing to help out.
