Thanks Sean

Swapping A arms side to side helps eleviate excessive camber too, how low are you?

Hi,

What sort of output flanges do you use on the gearbox for type 4 CVs?
I currently have type 1 CVs on the inner end, van running at approx standard height and have done approx 2000miles this summer.

from the wheel arch and taking a measure from the top and bottom of the wheel rim , 71mm at the top, 44mm at the bottom =27mm difference.
As for the ride hight, the distance from the rear arch to the garage floor is 470mm, i cant lift the bus any more because i am running drop spindles
and a T2 detectives beam with adjusters that wont adjust anymore, so i am stuck with the hight!!
Thanks Sean

Just been out and had a quick measure of mine.

Distance to the rear arch from the floor 430mm, so I can't get to the top edge of the rim, so I only measured at the bottom and half way up. I have 35mm at the bottom, and 43mm half way up, that's only 8mm, so 16mm overall.

I have Autocraft chassis legs (same as CE) and all bay derived IRS ('cept the box), the only consession to camber is the aforementioned swapping from side to side of the A arms. Wheels and tyres are 5 1/2X15 with 195/65x15

Just so you know, all Bay IRS parts upto and including '70 are the same, all parts from a '71 are the same too except for the hub carrier and brakes.

Like it as there is camber adjustment that you can dial in once its all fitted.

Don't the a-arms change at some point? Brazilian's are different as well aren't they?

Cheers Jim thats good to know. Be interested to hear any other opinions on them and pics of it fitted if anyone has them?

Would it be possible to cut off the old a-arm brackets and fit the ones that can be adjusted? Would that take the camber away? Just adjust new brackets and then weld in place or will the adjustment have to be done at the hub with the CE kit?
