[V8] Air Conditioning Q's

[Lanier Pratt]

Hey guys.  I'm new to this forum and so far you guys have had
a wealth of info. for me.  I am getting ready to do my timing belt
kit that I just purchased from Blaufergnugen.  They are temporarily
out of stock on the strut mounts.  Do you guys no of a good supplier
for the strut mounts?  They had the boots, stops and bearings, but
were out of the mounts.  I really want to get the right ones so if you
know of a reputable place with good pricing I'd love to know.

Thanks,

Lanier Pratt
