The shims used in the 907 were previously used in some other Lotus engine.  Possibly this was their twin-cam, which, IIRC, was used in the Europa.  (Or not.  I can barely spell Lotus and am certainly not an expert on them!  :^})

IIRC, it was Kurt Housh who discovered that Saab 900 valve shims also fit.  These, however, are listed with metric dimensions and come in 0.05mm (~0.002") increments.

The last time I checked -- two or three days ago -- the JHPS warehouse store was still offering JH valve shims.  If this is no longer the case, you can always contact Delta Motorsports.

$1.25 a shim was a fair price in 1990.  Expect to pay $2 to $3.75 each, today.
