I have a front cross member with R&P, but I don't want to lose my RB setup because it responds soooo much better than the R&P models.   
  
Also I have the trans cross member from the turbo car I pulled everything out of.  I also have the rear diff,  CV shafts, axel stub adapters, etc. etc...  I went into this with a pretty good idea of what I needed from the parts car.
