Hey Clint. That is a weak point on the cars. Are u using the manta Ray shock tower or the top force one. The best I came up with was using washers under the screws, I used machine threaded screws not self tappers and on the left hole I think, I ran a longer screw with a locknut on the other end which also doubled as extra strength holding the top cover of the gearbox down. Some of that might help. My manta Ray has been pretty bullet proof but I probably don't run it as hard as you do, mines been babied in 540

Just wen hunting for my 69 tooth spur. Typically, its in the truck up at the farm. Now I have to concoct some sort of story so I can justify a 4 hour round trip to pick up a $10 part 
Ah well, It looks like I've just scheduled a practice day at the secret test facility!

So has anyone got a spare madcap gear cover they r willing to sell? And maybe 70t spur? To go to the 26/27t pinion u need to shave some of the gear cover to make the pinion fit which i am not keen to do on a newish one. 25t seems to be as large as u can go without modifying the cover..good luck to any of u running at the nationals here in Canberra

Hi Mikey, yea it is just a really poor design on the rear gearbox housing, I had a look tonight and there doesn't seem to be any simple way to brace it 
I am building up a top force this time using some of the Manta Ray bits and possibly putting it in mod to
and I will be using machine screws instead of the self tappers as well
haha mine has had a harder life than yours because I my total lack driving ability
When some more bits turn up I will post some photos

I am worried now as I have just brought another gearbox set for the top force build up and am hoping that it is the late model one with the rite hole in it 
I am going to try and make some sort of plate and pin set up to spread the load of the shock tower mount across the 2 holes below the mounting holes.
I am sick of replacing gearboxes because the 2 mount screws on the rear tower have cracked the case, I have about 4 dead ones now
If I have any luck I will let every one know and mabey build a couple of extras

There was a running change in the gearbox casing to fit the Skyline Speed Tune gear set on the Skyline they released. Easy way to tell is a small letter H molded in the gear case ( High Speed ) All gearbox cases after that I think have this marking. Older versions were from the original Manta Ray & Top Force.

Thanks mate, I had heard that they were different but never had it confirmed as such.
The newest box is a red one so I will assume it is the skyline box, now I just need another red front one and I will start building
I have a brand new black one so was going to get another black one for the back but they seem to be hard to get ?

Here's some pics of my top force. The long screw with the nut was the best I could come up with

I used to run a TA02 for on-road. I'm pretty sure I remember being able to grind out a little of the top gear case so you can get screws through on both sides, although you can't use them fancy nylock nuts.
I like the way you think though Clint, cause success is all about appearances
