PARAGON has a little shameless behaviour in the past

I know we've talked about the a-arms but I found this bulletin from GM.




<FONT face="Arial, Helvetica, sans-serif" size=2>Engineering has changed the
design of the lower control arm used on C/K HD trucks and the HUMMER
H2.

The original A-shaped arms for the C/K HD were p/n 12475475/76 and
88982348/49 for the H2. The service arms for all vehicles are now the V-shaped
arms.

The V-shaped arms are direct bolt-in replacements and require no
special treatment; they simply look different. The new V-shaped arms are p/n
15103878/79 for the C/K HD and 15103880/81 for the H2.

<FONT
color=#ff0000>TIP:</FONT>
These are the production as well as
service part numbers and should not be mixed. The bushing rate for the H2 arm is
much firmer than that of the C/K HD.</FONT></P>
