sounds like youve been lucky then!
I had a quick measure up, the holes in the transom measured on the outside are 370mm vertically up from the flat of the center of the 3 chines, or measured down from the top of the transom 130mm down and 90mm out from the tube attachment collar.
The bolts in the floor are in the center of the raised section that i can see on your photos and 490mm from the transom base.
these measurements are approxamate but will allow you to find the evidence of the old holes. as far as i know all srs are slightly different as theyre hand finished.
