Hey guys and dolls. I am midway through fitting a 13btt from a series6 rx7 into my 84adm ae86. It's going pretty smoothly, but i was just wondering if anyone has done this conversion or is aware of any snags/problems to look out for? Mainly to do with the front crossmember in relation to the sump on the 13b. Do you need to make a new crossmember or modify the existing one? Any help, opinions, photos, would be greatly appreciated, Thanks, have fun.. cheers, crispi
