I bought my s14 notch top from Venus-auto.com in california. I got the whole clip and it came out to 3k shipped to a shop. The engine was in good shape, the only issue I had was the ecu was blown and had to get a new one from them. Dont know install price being hat I did the swap my self, but my local shop charges 4500 to 5000, I think. Hope it helps.
