Will it be too difficult to get the car back on the road? No, I don’t think so. Will it be without sinking a ton of money in to it and by the end of the year when my brother wants it as his first car? Well, that I can’t promise.
At current she will start and run, though she wont drive as something just doesn't look right with the accelerator cable gubbins (She was converted from Stoms to HS4s and the bracket is epoxied to the manifold for a start (pictured)), the auto box has leaked all its fluid away, the rear brakes are stuck fast (the handbrake isn't the cause here for once!) and the interior in general could use a good clean up.
Does the manifold look right, is it worth trying to work out why its glued and remount it or should I just replace it with the longer inlet when I get the chance? (I've heard this is a thing, better flow or some such??)
