RC10B3 measurements needed...

[Miggers]

Would one of you awfully jolly gents that has a B3 take some measurements
for me please?

If you could,I need to know the distances between the rear suspension
(3-3's)mount screw centres.

Ta.

Give me ten minutes and I'll have a look

33mm exactly. I presume you mean the centres on the actual part and not the left to right mounting holes across the car?

[Miggers]

Sorry Chill,I didn't word it too cleverly did I.

Yes I do mean the left/right mounting holes on the car.

Also,do the 3-3's fit slightly under the gearbox's outdrive bearing housings?
If so,then how high off the rear chassis plate does the gearbox stand?

Oh yes,and how wide actually is the rear chassis plate at the point where
the 3-3's/rear arms sit?

Thanks for helping.

OK, the front two mountings to the front of the car are 19mm apart, the rearward ones are 22.5mm to account for the rear toe in. Looks like the mountings go around the outdrive part of the gearbox casing not under it. The rear chassis plate measures 30mm and runs parallel back to just before the rear mounting holes then steps out to 32.5mm again parallel.

Hope you can get your head round that, if not we can do pictures!!

Cheers, Mark.

Ok mate,that info is just great,I have a B3 manual downloaded and I can
also read and work from engineering drawings,so relating those distances
to what I'm looking at is no problem.

What I'm upto is this:

I have a Mardave Cobra that has a complete B3 front end on it and the gearbox from a Madrat.
The rear mounts are cut from the Cobra's gearbox but had to be shaved
to clear the 'Rat box's bearing housings.
The Cobra has zero anti squat and zero toe-in as standard,so on slippery surfaces it wants
to write it's name in the dust as soon as you put the power down.
I modified the removed Cobra mountings to 3 degrees toe-in which has tamed it no end,
but the problem now is that it's pulling the screws out of them....

The 3-3's and a pair of composite B3 rear arms are to replace the Mardave
bits and should sort out the handling at the back end a lot more.
It'll be Mardave in only ally chassis,battery holders and body before long,
everything else is either Ansmann or Associated.

Thanks for your help mate.
