just talking to my bro-in-law and he pointed out a couple of things bout h190

it is a 8.75" diff

some series 2 rx7 drag car dude swears by them, he uses one behing his car putting out 700hp!!!

and remember at only 90mm wider than a stock 1200 diff you can fit em in nicely with fwd offset rims or flares, only thing you need to do is remove mounts and move them in a bit, and find an lsd

yeah, they are an execlent diff. there really strong and easy to get and are reasonablly cheap i got qouted a $165 from disc to disc from a guy in wang, but thats country wreckers for you. the only thing that lets them down is they are kind of heavy compareed to the std 1200 one, but the are just twigs, waiting to be snapped woth some datsun power.

what does the h190 come in?
and will it fit under a 120y coupe no wories?

the eaisest car to find them in is the series three bluebird. well this is what i found. to indentify just count up the bolts that hold the center in and if there are 10 its a H190. i pretty sure that is right. you will probably need to get it shortened to suit though.

vanettes have em too with 4:1 or 4:9 ratios

Did they only come in one lenght? Is it a harder conversion using one from a bluebird as oppssed to a vanette one? (Are they both leef sprung? I know I have to move the mounts anyway.)

my car has a vanette one, i also have bluebird series 2 disc over drum brakes installed into it, im not sure if bluebird and vanette are exactly the same though

the disc over drums go straight on and all brake lines match up ect ect, but i think the handbrake cable was lengthend

the bluebird wagon diff is about 50 mm (2 inches) wider than the vanette housing,which is again about 2 inches (50 mms) wider than a stock 1200.the axle spline sizes are also different,with the bluebird axles being bigger.you can also get an alloy housing 4.6
:1 diff from some vanettes,they're lighter than a h165 centre,& is what i've got under the back of the sunny.so take a magnet,& if it doesn't stick to the housing,grab the whole rearend,move the mounts in to suit,& it still uses the same length tail shaft as the 1200 ute h165.
p.s. i seem to remember that series 2 bluebirds were h165's,whilst the series 3 bluies were h190's.not too sure about series 1's,though.

i havent come across one of those bloody centres yet, but the ratio is wrong for the road car, and the rally car has the 165 diff

is the 120y track the same as the 1200 or is it closer to something else like an L series car like bluebird or 180B?
