Been doing some research on this. I have B18C GSR swap. I want to use my D-series lines. I have read that I must have P72 upper bracket. Also read that PR3/P30 upper bracket will work. As far as I know I can use either PR3/P30 or P72 for the lower bracket. I'm going to be using '99-'00 SI pump so I can use stock lines. So mainly I need to know can I or can I not use upper bracket from a B16a2????? Thanks for the help!!
