Why with all this mix match stuff? I Did the 5 lug conversion back in 2003 or 2004 with straight ITR. Did not use the ITR LCA for 4 years till I put in the ITR LCA. The only difference with the ITR LCA is you have to use ITR rear struts. I also have ITR axles. I did this on an Automatic (JDM SIR-G transmission).
