    Hi All, I have saw/read threads were many have drilled a new bottom mounting above the original so the strut will still lower. I followed instructions and measured the space I had between the strut and LCA. I had about 15 millimetres and to be safe drilled at 8 millimetres. You see from the photos even just that small difference would not all the bolt hole to line up before the strut bottomed out on the LCA. is there something I missed?

    I would think drilling it any closer to the original hole would not make much of a difference.

    You did a sloppy job of drilling it too high up ! You will need to weld it at least some ! If you can force it in , it will rub the bottom the strut and sgueak ! I have done about 8 or 10 Struts this way ! I only got one too wide ! Good Luck , Sonny

    Just spot weld a little of the top of the hole and re-drill or rattail file the hole !

    Thanks guys!! I measured the space i had from the LCA to the shock. the hole is only 8mm higher. Is there much point to drill so close together? I think it is the ACDelco professional replacement LCA's, they are much beefier that the stock ones.
    If i fill it in and re-drill it 5mm (0.197) do you think it would lower the front that much? For now i just put it back in the stock hole.

    Do you think I need to weld it back if I keep it in the stock hole?
