As an
outsider it never ceases to amaze me..just the fact you can go to your FLAPS (Napa,Autozone etc) and order/buy parts for these old trucks in the first place.
Here in the UK you'd be hard pushed to get anything from our local parts store older than 1990 European cars never mind a Chevy!
Mention that name here and they automatically think of re-badged Daewoos.

In saying that i've had good results dealing with U.S. suppliers,LMC included,more so than some UK based suppliers i've had experience with.
The main downside obviously for
us foreigners is shipping and timescale.
