Factory fan questions
 

Guys,
did the factory fans for a 1977 truck use a spacer or where they just bolted to the pulley?

I am trying to go back original with my truck and when I bought it it had an aftermarket fan.

They had a fan clutch from the factory. The spacer is only used with the flex fans.

IMO, clutch fan. I believe spacers were used to get the correct fan position in the shroud.
My '73 had an old fixed fan and about a 2" spacer.

I bought my 74 from the original owner, It came with a clutch fan with no spacers.....

quick question
is it true the old 4 blade fans were on some kinda recall?
my 78 burb threw a blade and it went threw the master lines to the valve/frame rail
of course after all new lines,heard bang leaving a light,engine shook like crazy,no brakes
rolled to a stop......was told about the 4 blade being common for this breakage?

my 76 has a clutch 5 blade fan and no spacer
