Seat bolts

[Blue C7]

Possible of interest. Made by cutting a piece of 25mm steel angle 50mm long slide in the end of seat runner and will hold bolt down while putting nut on below

One post per bolt seems a bit over the top :)

Maybe it's a four seater like the big Morgan

Easier to just tack weld the bolts to the runners.

My seat has a bolt missing

That looks a good tool. I had allen head bolts in the runners on my drivers seat, and getting an allen key in was a nightmare! I welded bars onto the bolt heads to stop them turning, but that was still a pain. Now I have made aluminium rectangular tubes for the drivers side so the bolts come up through the floor. There are two sets of captive nuts so I can move the seat forward so my wife and daughters can drive

I use M8 cap head allen bolts though the runners and nuts underneath and never had a problem. I have got long arms!!

I welded plain M8 nuts in the runners and bolt from underneath.

#7 ... cap head bolts for me too ... no problems.

Hex heads from underneath into captive nuts/steel nut serts/hank bushs in the seat rails. 

When the hex heads hit the ground, which with the lowered floor they do on occasion, there's not so much protruding to catch the ground.  When it does, and gets ground off a touch, there's still usually enough left to get a wrench around to undo it.
