MG MGA - Seat Bolt assembly

How are the bolts holding the seat "supposed" to be assembled?

Meaning does the bolt head lie to the outside or inside? Is there a washer between the head and the frame?

Likewise is there a washer and lock washer on the nut side?

Also I was thinking about putting a thin "curved" washer between the two frame sections (these are spring steel and often go between too surfaces that are supposed to pivot over each other to reduce friction) any experience here?

Thanks mucho to all!

T, the bolt goes thru the top with the nut on the underside of the car. I would suggest using stainlees bolts and large stainless fender washers. There is a lot of preasure on these rails from big guy's like myself getting in and out. Relying on the wood and a smaller washer is likely to result in failure.

Thanks Bill.

I was unclear. This is the bolt to attach the back of the frame to the base frame.

Tysen, I have just been examining my seat collection!

From the factory the bolt went through the seat base from the inside with a plain washer between the back and base (the back is tapped) and a plain nut on the outside. Sorry the picture is a bit blurry (must be this wine flu that's going around)

This is not the best engineered hinged joint I have seen! I would think an additional flat washer under the bolt head might be an improvement. However, I notice that the bolt length was exact for this application! It's common for the threads on the seat back to wear as it's not very hard steel, in which case you will, of course, need to use a lockwasher.

Can I have a bit of this wine flu? Sounds more enjoyable than the other version.

By the way I phoned up the swine flu hot line on the National Health Service (NHS) and there was crackling on the line. When I eventually spoke to a nurse I was asked if I had come out in a rash(er) or had the trot(ter)s.

Speaking of seats, try a spacer between the front of the seat and the rails to raise the front of the seat a bit. Experiment a bit and find a comfortable angle. It helped my back and changed the foot angle to a more comfortable position.

I just finished helping a friend install new foam and covers on some MGB seat and they had a thin steel washer between the seat back flange and the seat bottom flange. I think that it acts as a spacer to help the seat back pivot cleanly. I am going to try it on my "A".

Keith, that is how the MGA seat was supplied! see my post and picture above.
