the diff will need the mounts moved (possibly changed to 165 ones)

you can fit bluebird disc over drums from series 2+3+TRX blueys

will need to make a small bracket for handbrake cable and if you go discs there is a little mucking around with hydraulic lines

only real LSD option is to source a Topgear one from the first batch he did (technically some blueys came with lsd but being 35yo and i havent heard of one existing for ages it's not really an option)

i am running the vanette 190 in my road car with bluey discs, its big but it fits, that is from memory 90mm wider (45 each side)

i also have a topgear lsd which im planning to put in

but id like a skinnier version to allow different and fatter wheels

if you wanna sell or someone reading this has one i am keen!

only thing i am unsure of is spline counts on axles, would need to do some research before doing centre swaps or anything as there is a couple of different splines in H190s
