hey guys, the car is coming along and next on the list is sorting out the diff. i have the 1000 diff out of the car with the h150 not far from it. I just thought i would ask before i started ripping things apart if anybody is running this set up in their 1k? i have seen that there is a 2mm thick spacer plate on ebay specified for the h150/h145 hybrid, is that necessary? 
 
so the few questions i have are.
 
will the a10 tailshaft bolt straight up? or do i use the appropriate 120y one? or do i have to get a custom one made?
 
besides the adapter plate is there any other shimming that will need to be done?
 
finally, any tips or things i should make sure i do when doing this conversion?
 
any help is appreciated.
 
cheers!
