For those of you asking about cost...there are three separate Items to build these.

Item1 : Fixed cost whether it's 1 piece or 101 pieces, it's the same price.
Item2 : Fixed cost whether it's 1 piece or 101 pieces, it's the same price.
Item3 : I don't have a quote yet. IMHO This IS the Big Dog on the porch!

PM & Register ASAP, and hopefully I'll get the price quote by the end of this week.

The Item3 price will probably vary depending...
There's a certain amount of set up and labor for Item3.
If I do 1 set of four (front & rear) it will probably be expensive.
If I do 10 sets of four (or 2) this cost can be divided between all 10 sets.
When I get the how-many # I can use that # to get a quote and divide it.
That is why it's important to me to find out how many folks are interested.
I'll send an email to folks that are registered as interested & describe Item3.
