Seasons greetings, Merry Christmas and all that

The car comes with substantial modifications which have been done to a very high standard. I don't know anything about some of these hop-up parts and was wondering if anyone could help me identify them.
My questions are;
Does anyone know anything about these aluminium rear trailing arms?

I also got the instructions to the Delta Desert modification kit for the Yokomo and was wondering if anyone has pics of what the parts are meant to look like. Could this be the manufacturer of the rear arms? Oh the alloy arms are mostly likely American in origin as the fasteners are all Imperial thread.
There is also a very fancy ball bearinged black frp cantilevered chain tensioner attached to a black frp spine plate. Does anyone know the manufacturer?

Finally up front there are some nice lower Hot Trick arms, Hot trick front dual shock mount, and rear bulkhead. At the moment as I am one shock short of a dual shock front end, it is using a set of CRP front mono shock mounts instead of the Hot Trick dual shock mount which is also mounted.
The car came with no rear shocks or steering turn-buckles I have added some blue rear Yokomo shocks and also some hop-up captured ball joint turnbuckes.
So here it is, with the shell on;

From the top;

From the back;

Anyway, feel free to comment on the car for example the relative merits of the modifications e.g. the massive alloy rear arms.
I am after any information about the manufacturer of the rear arms. Is it Delta?

Anyway thanks for looking.
Cheers

P.S. If anyone is after some parts for this type of car, either the, Yokomo YZ834B Dog Fighter, the RPS Yokomo SE or the Wonder Dog Fighter then get in touch as I have a ton of parts spare which could help you out. Oh I am also after parts, so lets trade!
