Also to note is the handbrake cable outer waving around by the selector shaft and the end of the cable tie used to fasten it to the chassis!
I looked at the front linkage for the handbrake and noticed that the lever between the pull and the cable looks bent downwards so the cable to the rear scrapes the fibreglass. Is this typical?
Also how is the handbrake balance inside the chassis supposed to be routed? It is clearly rubbing on one of the heater/radiator tubes.
The translator looks to be the correct shape, you are correct that it and the cable shouldn't rub on the fibreglass. From memory it's fixing into the chassis looks to be a threaded tube that sits proud of the chassis by about 10/15mm, the top edge should be about level with the fibreglass of the body. The translator sits on a washer on top of this tube with a sprung steel type washer under the bolt head. - Check to see if it is assembled correctly?
If the felt material that goes between the chassis and body is too thick it can affect the above as the shell sits slightly higher which can make the translator rub on it just like in your picture (have seen this before also!) - it's not practical to suggest that you remove the body to investigate that particular one so a work around is probably best!
There looks to be some sponge foam in and around it that I don't remember should be there (does anyone have this in their car?) which doesn't look like it will be helping.
The wires need re routing as has already been mentioned.
It is possible to open up the slot in the fibreglass to create clearance for the cable and translator but it's best to check its all assembled correctly first.
The handbrake balancer should be underneath both radiator tubes, looks like somebody has struggled to get everything assembled correctly (maybe when replacing a cable?) through the oval access hole in the chassis. It is likely to rub slightly on the bottom of the radiator tubes when the handbrake is pulled on but this will be minimal.
The adjuster is a real PITA to get to!
Looks like you have quite a few jobs to attend to or investigate, nothing is overly difficult and you will enjoy it all the more when it works even better as a result of your efforts.
