all u h165 ute boys can slip bluebird disc over drums straight in, and they hook straight up to everything, you just have to get the backing plate swapped onto your axles as this requires a 4 ton press and new wheel bearings ($70)

i have a pic of it in my photo album on a h190, havent done it to my 165 yet though im told it works and i cant see why it wouldnt, only thing is these puppies require minimum 14" rims

[edit] i did put vanette h190 drums on my 165 as they fit inside 13" rims and are much bigger than the 1200 rear drums
