    For reference - the standard inertia reel mounting point is the bolt adjacent the extinguisher bottle ... which, when compared to the Willans installation guide is too far back.

    Does this help ?

    Did you get them from demon tweeks & are they a captive plate you weld on then screw the eyelets in?

    cheers

    The eyebolts can be sourced from DT, I secure them using a `non welded` plate that is tapped with a 7/16" UNF thread to which I add a 7/16" UNF Nyloc (except near the exhaust). These plates are also available from DT and are different to the `weld on` plates that include a captivated nut.

    Seat tubes are now fitted on both sides. The original seat rails were very well attached to the car so we cut the top and bottom section off from them and left the rest spotwelded to the car. In the pics below you will see we didn't use the extra plates in these locations but did on the drivers seat forward tube as it is welded onto single skin.

    Drivers forward tube, cut to shape and plates shaped to fit:

    I thought the kit was very good and made the job quite easy.

    thanks so much for that lads, steve why do the end plates have holes in them before welding?

    Not too sure, maybe so the tube is welded directly to the car as well as the plate.

    Makes my bolt seat rails look far too complicated!

    Weld in rails a job for the winter I think.

    Steve - what were DT's tube diameters, tube wall thicknesses and tag thicknesses out of interest? I'd guess 3mm, possibly 2.5?

    My Mk1 has tag thicknesses of 3mm, which are Custom Cages.

    Tube:

    OD is 2.54mm / 1 inch
    Wall is 1.65mm / approx 1/16th inch?

    Plates are 1.46mm.

    I ended up getting some 1 x 2" box tubing 3mm today & some end plates also 3mm.

    will have to diet to make up for the extra weight :lol: .

    Which part is the heat shield? [:$] & is it ok to just weld these straight to the tunnel inside the car as it is in the mk1?

    I put them on the underside of the tunnel - saves MIGing

    Do you mean from the outside Chris?

    Does it matter which way these go on, in that does the nut part have to go within the wall in a recess or can the nut face outward towards the seat?

    My Mk1 had an exhaust heatshield in the centre tunnel, I removed it when I used the type of fitting below. I did not use the larger type fitting pp your post as it does not fit the curvature of the tunnel.

    I always fit these items from below (outside), I don`t weld them.

    The fitting you have referred to has to be installed with the nut `away` from the eyebolt - see the Willans guide below.
