    I repositioning the front damper mounts on the track control arms by welding bushes a few mm's higher than the original mount points. I had to do this as I replaced the original steel dampers with Protech alloy 400 series dampers. The alloy damper mounts require more clearance. The Protech dampers are 1.5" shorter than the original dampers. I had far too much droop and needed shorter springs to enable me to achieve a lower ride height.

You don't really need the spacers as each bolt prevents the clam moving left or right. One day I will probably get around the fitting them again but every time I remove the front clam they are a real pain.
    Thanks Paul, think yours is different to mine, or mine is wrong, I attached a drawing of the setup, but the bolt that goes through the frame goes into the threaded both sides bolt then the clam, then a washer then the large nut

    But the bolt is not threaded in the frame so tightening it or loosening it just moves the bolt in and out, doesn't affect the position of the part that goes through the clam, any ideas

    I think the idea of the big ( M20?) bolt and large diameter washers was to allow some adjustment of its position in the fibreglass. You drilled the fibreglass oversize, assembled the M20 bolt, washers and nut, then adjusted the position of body against the pivot point in the frame before clamping them up tight.
    On Frederics car I just used the bolt through the frame as a pivot point and didnt fit a nut. I drilled it through and put an R clip through the bolt shank on the inside of the chassis pivot tube to stop it sliding out. To remove the front end then you just pulled the R clips, slid the bolts out and lifted away.
    I dont recall a lot if effort to get it all lined up but maybe I was just lucky. I had done a fair bit of re-shaping on the front clam so probably got rid of mis-fit there.
    If you have enough thread on the M20 bolts you could add washers behind the bolt head to align the clam laterally, then use the pivot bolts as I did.

    About right, the clam is over drilled and I have movement up/down etc, but it is not moving the clam around to the left so the rear left tip of the front clam is too far forward from the door aperature

    Think i will get the fiberglass out and re-profile the trailing edge of the clam to make it look right

    I think that was more or less standard practice on Corse bodywork, Steve.
    Probably a lot less trouble in the end.

    My clam has about 12-15mm of clearance, each side, between the 'Clam' and 'Frame' in your sketch. I have simply tightened one bolt until there is 1mm of clearance on one side, this moved the clam 11-14mm to the right in my case. This was all I needed to centre the clam on the windscreen.
    Looking at your drawing I would have thought you could do the same?
    If the tube welded to the chassis, is the only thing preventing the clam moving sideways, I would consider grinding this in preference to playing with fibreglass.....

    I have now completed renewing my suspension setup. I have fitted new Protech front dampers and my refurbished Leda rear struts. With shorter springs I now have been able to set the correct ride heights after driving around an elevated car for the past few years. Thanks to Craig for helping me to make the correct spring choices.
    You might be amused to see my rigid rear dampers....Click image for larger version.

    What size is the engine? 2l?

    Sounds very similar to my 200hp k-series rover (on ITBs) that I had in the Lotus 340R. Lovely noise.
