if i can manage to find a steel diff do i have to put the original gears back in or will it just bolt in also mine is a v6 2lt if i put the 1600 diffs in it will it drop my gear ratio

quarry pits hey,heard down the pub u done that today at club champs

The 1.6 has a different spline on the driveshafts and different (lower) ratio diff. Easiest solution would be for you to fit your internals to a steel diff housing.

yeah man gave it to much herb and snaped the weak cast housing ah wel build it harder so sumfin else breaks

do you know if i put the raer diff in off the 1600 and the front end of a 1600 ie cvs hubs etc will the go in or are the drive shafts different to i need to slow it down a bit

True on most cases but you can get 26 spline 4 cylinder diffs, but kernels is right, swap out the parts want to use. You might need to gat the pinion setup professionally. Use 5.12 ratio diffs as they are lower and better offroad with bigger tyres, it's a worthwhile change.

where do i find the 5.12 ratio diffs

You can have the 26 spline side-gears from your current diff swapped over to a 5.12 ratio diff from a 1.6L

If churchill still has the 26 spline 5.12 front locker for sale that could be worth the money too.

so if i take the internals of mine i can mix it with the internals of a 1.6 and get it lower geared provided i take it to someone who knows what they are doing

Correct, swapping bits of diffs require a few special tools and a bit of know-how, but shouldn't be too expensive.

if i do the front do i have to do the rear

Yes, diff ratios have to be the same front and rear otherwise damage will occur.

I do have a 5.12 alloy front diff with an air locker in it if you're interested.
It comes with Warn free wheel hubs, full set of cv's and axles plus spare cv's, a nylon bush on the rhs inner cv to stop the oil leak they're prone to and new seals. $1000, pm me if your keen.
