So question...

I have a 91 Silvia with the super HICAS rear subframe. I bought the lockout bar, but just found a pretty good deal on a standard USDM S13 subframe.

So before I clean it all up, put on all new Energy Suspension bushings, and the ISR suspension kit, I need to know a few things...

Are the subframe mounts on my Silvia all in the same position for both subframes??

The USDM one came with an open differential. Will my stock LSD that’s on the super HICAS bolt straight up?

If so I’ll probably weld the open diff to lock it, and have the ability to swap em out as needed.

So yea, the big question I have before I begin, is if it’s just a straight swap and if all the bolt holes line up on the main subframe mounts.

Thanks.
