Here is my cure for the BBK shorty fitment issue. On the right is one of 4 stock m10-1.50-15mm hex head flanged hex nuts that retains the stock mid pipe to the stock cast iron exhaust manifold and or shorty headers. Due to the flange on this nut will not fit with the BBK shorty header, there isn't sufficient clearance between the stud that comes up from the mid pipe through the collector flange, the collector is too big or needed to be dimpled for clearance. Substituting a non-flanged m10-1.50-15mm hex nut ( 15mm socket size ) will fit BUT due to the too close proximity of the points of the 15 mm nut to the collector ( approximately 1mm ), it is a very tedious ordeal to tighten these nuts with very short open end and crow foot wrenches being the only option due to the space constraints under the car and headers. The nut on the left is a stainless steel ( polished to boot ) m10-1.50-12mm 12 point head flanged nut ( 12mm socket size ) I purchased from allensfasteners.com, p/n 400-8345. In SS they are pricey at $3.72/ea but in standard steel they are $2.83/ea. The short 12mm, 12 point combination wrench pictured is a Husky Pro but all tool manufacturers produce a similar short 12mm combination wrench. Had BBK included 4 of these nuts with their headers, gaskets and header bolts I guess this and the thread I started on BBK shorty headers fitment issues would have never been.
