Te51 lift back suspension questions..

[Te51sr5]

So I got a 77 corolla that I'm rebuilding from the ground up and I got a few questions. While I'm in there I want to upgrade the suspension to be a little bit stiffer but I don't want to use to many after market parts other then bushings. Is there parts from any other car that can fit or made to fit that would be a upgrade over stock?? I got to so having to do some fab work is ok. I'm not trying to get this car done anytime soon. Any ideas or info would be awesome. I'm trying to make this car to be handle turns better then it does now. I already did the front ae86 disc brake conversion. Thanks in advance..

Oh and is there any rack and pinion setup that would work to get rid of the steering box, that would work with the t series engine??
