Dovetail Question

[Hans Tucker]

I purchased a set of 155mm SoCal rings for my APOMAX but alas they are to small so I have to default to the original tube rings which have a 90mm wide mounting bolt spacing. I can't find an off the shelf dovetail that has this spacing..anyone come across any wide space dovetails?

I have a BT Tech Large Takahashi Dovetail Plate which has three set of holes with a spacing of 90mm and separated by 100mm and 280mm {m8x20 bolt}

Had a look at a Losmandy universal plate with latest bolt pattern, the widest holes just under 90mm
