Hi Steven
It's not for the faint of heart, but these fans can be rebuilt.
When I bought my '62 TR4, the fan had several cracked and/or chipped
blades... and it was on backwards to boot. I drilled out all the rivets and
used the best blade as a template to make four new ones, each about 1/2" longer
than the original (for just a bit of extra cooling). I carefully pressed each
piece against the curved back of a shovel blade to get the airfoil shape, then
used little button-head grade 5 bolts and stainless nylock nuts in place of the
rivets. Static balancing (adding and removing washers) seemed to work pretty
well. Looked pretty cool too with all the stainless nuts. :) Car still
overheated. :(
The plastic fan is probably a better bet.
