Is Rulon going to have his 505 back on the road before mine?

They sell micrometers at Sears and thru mail order. Summit racing maybe?
Get a good one. Lowes sell some but they are not usable, IMHO. Cheaper
than the ones I used in high school...

I put standard size rings after removing the old ones and cleaning
the piston ring tracks real good (Autozone has a tool for that).
The ones I got are Deves, any import shop should be able to get you
some, but the usual suspects (tm) have them in stock, that might be
a faster solution. Note that they are at least $200 per set (compare
that to the same type of Deves for the Lancia for $50...)

Do you see oil on the turbine? You could always have someone rebuild
the turbo for you if you want to be sure.
