Bolts For R33 Gtr Diff

[20's_plenty]

hey guys i have a r32 gtr rear end in my 180sx im using a r33 gtr v spec diff (active lsd one) and the orignal bolts from my r32 gtr diff are to big a bolt for my r33 gtr driveshafts (the 6 bolts that join driveshaft to diff) are they a special bolt? seems like the have to be very thin around the head to get them to work does any one have any pics of what i need? or do i have to change drive shafts to r33 gtr ones?

ive tried allen key bolts in high tensial and have ground down the heads and they just fit but would rather use the correct ones can anyone please help!
