As for package deals... I haven't scoured the net yet, but I do see a Detroit Speed kit series in the NPD catalog. Level 1, 2, 3 ($2090, $2653, $3650)
That final $1k jump is just with the addition of tie rod ends, tie rod adjusters, and a steering gear with rag joint and pittman arm. Could that legitimately add $1k??
