The steel wheel ct26 of the 7mgte they r easy to find and the only require the onld manifold to be machined down and a new plate put on as the holes are slightly out i got mine done for $50 plus ull need to modify the oil lines but its the cheapest option. I will have one for sale its high flowed in about 3 weeks with manifold and oil lines dump pipe etc out of my carina so keep posted
