Ok out there in tech land, we had our monthy race meeting and have become stuck on a subject. Is a t bucket a convertible or is it a dune buggy? under nhra rules
I side on convertible as i have one, then roll bar limit 13.5
A dune buggy needs a bar to even be on the track.
my other argument on this is there was no rollover protection built into any convertible until into the 70s, and that if a bucket is a dune buggy so are most early convertibles.
no one is really shure as there are opinions on both sides

I have seen t buckets at the tracks before with no roll bars but like mine they were not really fast down the 1/4
