I'm doing a 5.3L LSx swap into my Z31 300zx. The motor mounts that I'm in the process of building are looking just like the swap mounts sold by Sikky and Daft Innovations. Does anyone have a set of them that they could measure so I can see if they will work? I'd like to know the length of the arm going from the block to the crossmember, with and without the rubber bushing installed. Thanks.
