ill keep this nice and simple. i have a hz holden, and i am currently borrowing a set of seats from an 80's ford be it after market,

the rails are incompatible with the floor and the rails can not be swapped as the bolt spacing on the seats are different. i can either re drill the holes in the base of the seats to fit holden rails or buy after makret seat rails(if they fit)

i realised that unless u retain teh factory seat rails an engineers cert is needed, that is ok as i need to get some things engineered anyway. in general do you think re drilling 2(possibly 4 holes) providing the seat chassis(i guess u can call it that) is the same thickness right the way thru? i really like these seats and i really wanna make them work...

Something to ask your engineer. This relates directly so safety, and they'd be the ones who know what would impact on that system, and how to modify seat rails to be safe accordingly.

i dont have one yet oh well. ill go into my local speedshop and see if they have like seat rails for the sparco buckets etc and see if they fit, despite being non standard, if they arnt "modified" then it shud pass much easier.

it would be easier to get modifications to seat rails or floorpan engineered than to get relocated mounting points on the seat passed....

ok thanks for that... will lookinto it. trying to plan ahead interior/stereo will nto start till after paint/panel and the neign goes back in stronger and shinier... thanks!

can usually buy rails that bolt onto the seats and the original mountings...

depends on the seat though i guess.

thanks sword, as soon as i can get transport(cant carry a seat on a pushy can i?) and i got a damn puncture yesty AAAARGH I HATE not haveing a car!!!

as soon as i can get a lift in town ill go to the speed shop and get some measure ments.
