Thanks heaps DatsAndy. That what i thought, i read off the rta site that if i use original rails and that, its an 'owners minor mod' and they dont need engineering.

30mm spacer you should be able to get from a speicialised bolt supplier, blackwoods is where i get my stuff from,

Nots 'n' bolts get them from the same place, and you want high tensile nuts and bolts.

I'd go for 50mm x 6mm flat bar, no chance of any warping or bending in an accident.

I wish i had a pic for you,

i removed the seat mounts & welded 25mm or 30mm anlge to the new seat rails, so the angle sits on the original datsun mounts in the car.

how i did mine

got some 5x50 flat plate, drilled holes so that the flat plate bolted to the seat, one plate across the front and one across the back
then drilled holes so that the flat plate bolted to the original seat rail

the width of the steel you get will be determined by how far apart the front and back holes are on the seat compared to the rail, as the plate obviously has to be wide enough for you to be able to bolt it to both

Thanks PIGDOG You put it in a nut shell there. 1 across front and back bolts to seat then bolts to rails. Don't use RHS your seat will be to high i reckon.

i actually dont mind it been high, im quite a shorty haaha. But im gonna go get some flat 5x50 right now. thanks for the help guys, il let you know how it goes.

recess 50mm x 50mm box section into the floor and weld it in. Then make provisions to bolt the seat brackets through them and the floor.




there aint no way this bugger is going to move hehe

hmm. wow i farked that up. and i ran into the same problem as last time. when i bolted the bar to the seat, there was no room for a bolt on the other side to bolt the rail to, make sense? hmm now i gotta go buy another two lenghts... anyone got some picys?

how i fitted my seats

Thats exactly what i trying to explain, thats the best way to do it, i had no problem getting my SAAS seats engineered with my CA18 coupe, it was exactly the same principal as in the phooto above.
