Here is the description of the Hybrid that I built at the time, I'd forgot about it being referred to as a BK2.5, when I put it up for sale:
"For Sale XXX BK2.5 as Chris Doughty's TQ car from last 2wd National, built up from ground up around a brand new plastic chassis with graphite VLA arms, towers, new front plates, etc, Lunsford T/buckles, Ti screws, modified chassis with bulkhead cut out to move cells forward.

Kind of wish I'd kept hold of that one now
