Wow, that looks great. How much were they?
This is the template I used, adjust it for your use. Welding is require, bolt and nuts won't work. We used strip metal, and 1x2 metal tubes. I can take pictures later.Did you take any pictures or measurements of the brackets needed to install?
Did you need to use any of the parts from the Insight seats? I'm thinking of putting on the black and red leather rx-8 seats with power and heat and am wondering if I can sell the old seats or if they will be gutted to do the swap.
