Just done some searching and havent really found much. But: 1) I have a V8 diff I want to put in my car, and as we all know they have 3.08 gears. Will there be a massive difference between the current 3.45 ratio and 3.08 ratio to the point it will be worse? 2) If so, Will the 3.45 gears from a N/A diff (with 25 spline axles) go into the V8 diff? (with 28 spline axles). 3) The diff is currently an open centre, now for me to change it to LSD do I just buy an LSD to fit in the current gear set or do I get a complete centre with gears and LSD etc and swap the whole lot over? I do realise that changing from drum to disk requires changing a few bits here and there, I do know what needs to be changed and I have all of that with me already. Thanks for the help Sean

Anyone help me out at all? Would like to find out by this weekend so I can do the required work.. Ta

You need the 28 spline LSD center to fit in... The 25 spline wont fit from what i can tell anyways...

Hey Hingo can u plz tell me wat i need to change to Discs from Drums Plzzz? Jim

I think your trying to ask if the gears fit onto your 3.08 centre no?

Yeah I am.. Its aiight, I found out everything I needed to know. Thanks anyway guys... Now I just need to find either a spool or LSD to suit asap... Will just stick with the 3.08 gears and just see how it is...

If your after a spool Pm JET-6 Some original photos have not been recovered yet.

Can any1 answer my question???

Also a handbrake cable they are different. Think thats all, try the wrecker VN's are the same i think. A whole disc diff from my local wrecker is about $100 including discs and all, could be the easy option I would suggest re-machinging and checking disc width and a new set of bendix pads also flush the brake lines.

Will just stick with the 3.08 gears and just see how it is... i have 3.08 gears in my vlt and the speedo's out like a mofo like 50's really 60 80's really 100 you can get it adjusted but not alot of places do it i think there's only like three places in melbourne and i will be changeing myn to 3.45 soon cause its the best ratio for vlts from what iv heard and the speedo's giveing me the ****s

Oh yeah, fogot about that! I've been told by someone on another forum that I can change the gears from N/A to v8... I dont see why it cant. Can anyone shed some light on that please?

yes I would like to know this too. I have 3.08 gears in the new diff i have bought. Can you change from an N/A vehicles diff (25 spline) to a 28 spline diff gears. Or are the gears different?

Bump?

all crownwheels and pinions will fit from 25 spline to 28 spline vice versa

all u do is change the gear sets there all interchangeable just dont forget u need to change both gears the crown wheel and pinion gear and the shims are the same from 2.78 to 3.55 so u can install the gears yourself im not sure if there the same all the way up to 4.11 as ive never srtiped 1. the crown wheel bolts are oposite thread so dont do what i did and keep trying to undo it when actually ur doing it up and snap a bolt.... u cant use a 28 spline centre with 25 spline axels it just wont work aswell as the berrings and the caps are dirent sizes for the 2 difrent spline centres hope this helps

Thanks guys... I got it all sorted with a whole new centre out of a R31...

BOOSTED WAGON ROFL i did the exact same thing- with the stupid reverse thread, it had me ****ed for 10 minutes! "why the **** are all of these so damn tight!" lol ohhhhh reverse thread i guess its so they dont work themselves loose under inertia

I was saying the same thing but still un-doing them clockwise. Definately would help to crack all the bolts before removing anything from the centre.
