If you are considering an LS Triumph wedge swap, please use a TR7 and not a TR8. Only 2750 factory TR8's were built. The price of factory TR8's are going up.
There was over 100,000 TR7's built and they are cheap to buy. TR7's and TR8's are the same car. The only difference is small items rear gear ratio, gauge cluster, decals, and that is about it.
