Have you done a stress analysis for this?

Your hole size and the proximity to a weld are going to concentrate the stresses a lot especially if you do countersink them which sounds like a disaster. Three smaller fixing bolts might work out better than two big ones if you do the math for your available area, as you want to design it so the fixing bolt fails under load before the frame does.

Your main problem is going to be getting them parallel. I'd use a threaded axle with nuts on to bolt the track ends to, keep adjusting until width is perfect fit inside the rear spacing then assemble a jig around this and rear of frame for marking up and assembly.

There is not a right way for doing something wrong, just less wrong ways of progressing towards A+E

Fire up solidworks!! was thinking the same but can't be bothered to start mine

I understand the budget is tight but can't you just spend £10 in aluminium dropout and pay £40 for a welder to do it? Much easier/faster/safer.

I think the key here is budget.

If you start paying for work to be done by a third party, you might as well get the FD hanger removed, rear brake bridge sorted, welds smoothed, headtube changed to tapered, etc... Then you have smashed £300-£400 so you might as well buy a used aero track frame.
