Lyndsay Porter's 'Guide to Purchase and Restoration of the MGB', republished
as 'The MGB Restoration Manual' is best for this, what follows is a summary.
Use adhesive that gives you a bit of slip. And definitely a hot garage.
And make sure you have the correct top before starting to fit it, the
gutters should fit close to the top of the drop-glass.
Mark the centre of the material (between the two seams) with chalk. Apply
adhesive to the middle third of the rail, which should be attached to the
screen, and the corresponding part of the top. Pull the top material
forward, aligning the chalk mark with the screen steady bar, taut enough to
remove wrinkles. Ensure the gutters line up evenly with the tops of the
door glasses, sliding the material one way or the other on the rail to do so
(hence the need for slip). Put more adhesive on the corners of the rail and
material, and pull each corner forwards and outwards just enough to remove
any sags and wrinkles. Fit the draught excluder corners onto the rail using
the screw and cup washer each side. Glue the front of the material onto the
face of the rail that sits on top of the screen frame. Glue and screw or
pop-rivet the channel for the rubber seal strip to the rail through the
material, and cut off surplus material. Ease the rubber seal into the
channel. This should be very slightly 'handed' in that one way round the
two 'bumps' in the seal that contact the top of the screen frame are
slightly forwards and the other way slightly back. I have found that if at
the back they get trapped by the lip on the top of the screen frame, whereas
if fitted forwards it shuts cleanly. With the rail clamped to the screen
fit the 'cocks and hens' to the tags in the material to line up (with a bit
of tension) with the male part of the press-studs fitted to the top of the
screen uprights.
