Gordon, you want some flares like I have on my standard CF hehe not sure if I have the photo of them on here, but they are just a strip of rubber I got from para rubber and screwed to the wheel arch as I had to cover the tread for the cert.
I'm running 235/70/14 on the back

Jesus, I'm running commodore dash which is eletronic

Bas, I'm going to take the van down to Hamilton again next weekend again and see how it goes. Will get gearing right before I sort speedo out.
The van has a full tank of petrol and some "stuff" in the back so is pulling some extra weight, will be empty for the nats (can dump it all in the garage when I pull the custom van out), hopefully it will cost less than $67 to get there and back

David have you thought about running 15's on the back...... Ok I now see your running 14x 70's so not to far off.

who has an electric speedo? Bedfords at least have a mechanical speedo

rocket has one of those jaycar ones.

But from memory, hq steel rims are scarily close to the springs and guards with a standard width diff

i have a banjo diff in a van here and the walls of the tyres are about 10mm from springs but whats wrong with that? if the tyres touching the springs there is something dramatically wrong already..

Now these would look nice.................... 15x7 - 15x8 - 15x10

Busy, try a arfter market Harley shop, or punch up Zodiac on the pc, we sell a few of these, sorry to say that l refuse to do electrical stuff so not quite sure if their compatable. They come in 1 to 1 or 2 to 1, hope this helps

Bas, I was wrong, my rears are 235/60/14  not 70 series but they aren't much smaller than the original commodore 15's

Thanks Rossie I'll look into it

[Bas NZ]

Ok, on the camper I run 275x50x15 on the rear and 205x75x14 on the front, they are close to a perfit match, considering how many rotations a wheel does it plays a major part. I guess it does not matter what the holden runs as you have proven this with the diff ratio, as if that was the case you should of been ok.

Food for thouhgt...Bas

Hi all,
Yet another queery about diffs,   i've just acquired a diff with a chev center,  i've been told its a 2.92 ratio and it will be going into my van which runs a Ford 302 with a c4 trans, will this gearing be too tall I'm running a standard Beddy diff at the mo and the poor thing is revving at 2500 at 80 kmh, and with the standard diff i get into 3rd gear before i even leave my driveway!! 
I have 14"x7" rims but havent decided on what rubber to run yet, obviously this will make a difference too, anyone have any recommendations on tire size
Stuey.
