A couple of years back I replaced the speedo on my 88 GL. I also went to
a Michelin XCA 205/75-R14 tire. On all subsequent speed /distance checks
the speedo is, as the little girl said - "Dead-on balls accurate!" . I
can't say much for the gas mileage though., at the moment. There are
some O2 sensor issues that have not been addressed yet and I have the
thing disconnected to allow smooth running, otherwise, it bucks, snorts,
and kicks a good bit - and its a brand new O2 sensor. I'll get to it
eventually.

Regards,

John Rodgers
88 GL Driver
