now questions:
HARNESSES:
at the moment, the eyelets for the rear of the harnesses are bolted straight to the floor, with nuts on the underside of the car, is this safe? i would prefer to weld a bar across the inner arches and the strap them to this! ideas?
where they are bolted to the floor is far from safe, mount on the old seat belt mounts
BUCKET:
bucket seat not currently fitted, need to either adapt the existing runners or fabricate something else!
looking at other peoples, welding new bars in and the attachin new runners seem to be the way forward! again, ideas?
yeah, thats the way to go 
ENGINE:
is the oil filler cap really that loose cap just above the throttle body?????
yeah, its breather/oil filler
we aim to be on track on the 19th december, full service, bodywork, seat mounting to be done before then, and the track day will be a shake down to see what is needed, with mods coming next year as and when we have the cash!!
