Core Support Cushings

[starman13]

71C-10 I have large holes on my Chassis. I ordered energy sus. kit all included
cab mount set.3.4108G SAYS 67-72 (suspect already) So I ordered from Truck Shop top pic Energy middle T.S. bottom compare.
My question is on the shoulder that fits in the hole on the chassis. the hole is
1 3/4 "The shoulder is 1 1/8 on Energy Sus. The truck shop ones are 1 1/4 is there
one that fits better in the hole if not what sets the position of the Core Support
In the last pic I ripped from another post.
Is this What it is supposed to be like?

You do. The mount bushing is smaller so there is some adjustment. Factory rubber bushings are the same way. IMO the more adjustment available the better.
