I have a 1995 sc300 with 2jzge. I'm about to do the auto to manual swap and I have a full w58 swap from a mk4 supra. Only mystery is I have no idea what crossmember I need? I've searched and found nothing but classifieds

 

I used a complete w58 swap from a mkiv. And I used the cross member it came with.

 

^^ Yep. The SC 5-speed and MKIV 5-speed cross members are the same. Either one will work. The rubber transmission mount is also the same part for the SC300 5-speed and MKIV NA 5-speed.
