how similar are 80/gq front arms at the diff end?

basically ive started putting the gq diffs under the bundy .............................just measureing up and hacking mounts off old gq chassis at this stage


the factory shock and coil mounts from the gq will line up perfectly, but the mounts for the arms to chassis have no chance......... they need to be directly under that chassis rails of the bundy (yes the bundys rails are wider than the gq's in the centre of the car :S) i cant move the arms inwards on the diff due to the pumpkin nor outwards due to coil mounts.

so what i am thinking is if i could use 80 arms mounted under the rails. otherwise i will have to adapt the gq mounts to fit under chassis kinda like a drop box this will lose alot of clearance tho

it aint that much clearanceloss, mine is 100 mm by choice, last one was 70. just make up a belly plate like DAZ off the forum did to his 40 when he coiled it. looked the goods and also appeared to work quite well (judging by the dents in the bash plate)

80 arms are different at diff end, i would just make a drop box set up they would only need to hang down 50mm or so. lots of patrols are running them with no probs hanging up

a few people have experimented with bending the radius arms inwards and mounting the chassis bracket more inboard. i believe flex is improved. i think bill (daddylonglegs) and sam (Strange Rover) did this from memory.

I thought that was only possible with Rover stuff. Thought I heard that Nissan and Toyota are to brittle to bend.

If bending it inwards was simple and the arms would keep there strength. it would be easy as, the bundera factory mounts are on the inside of the rail and at the right spot.

A bloke from the Surf forum did this too... heated up Bundera arms for more drop and correct castor, then got them x-rayed for the engineer and they were fine, pretty sure he is on here too, hales12371 or something of the like

You can do it with Rover arms cause they are forged, nissan and toyota arms are cast and should not be bent.

looks like you either have to modify the chassis mount to suit a gq arm, or modify the diff brackets to take a bundy or rover arm. are the diff bushings the same width between gq and rover? maybe a redrill of one hole is all that's needed to use rover arms?

I can't say I have ever measured that, but I have one oh each in the shed, I might have a look tomorrow.

could be an interesting proposition using the rangie arms

i would like to do something that still looks pretty factory. at least untill the engineer is happy

Bending arms is all good if you do it right.
The Bundera arms I bent are made from very good material.

the std gq arms on mine broke so god damn easily i would now be scared to drive on standard arms. I was using it as a lever to rotate the diff to put a bolt through the 3rds arms and it snapped under little more than double the weight of the arms itself. the inside looked like 20 grit sandpaper

yeah i know the factory ones arent anything special. but engineers seem to think that they are the only way. so ill roll with them till it alteast has mod plates n rego
