'86 Turbo suspension on a type 3

A while ago I got an '86 951 suspension set up for a type 1. As far as I know the trailing arms and spring plates should be a drop in replacement for the original type 3 arms, just like they are for type 1. Is this right? I also have the front brakes installed on type 1 spindles. Are the spindles a bolt on item to type 3 front trailing arms? I know these are all lame questions, but I've been out of VW's fo a little while and can't remember what interchanges easily with what.
