So Its been FAR to long since I originally posted this ~

Bars (or Brackets to be more accurate) have been well received and at the tail end of my 2nd (small batch ) production run.
As a bonus since the rear mount points on the Bracket are identical between the 914 & (early) 911 It can be used on either.
Lastly pricing has DROPPED from the original post. $129. + 26. shipped in the CONUS
