See this photo for the bracket I am talking about:
http://www.gmcmhphotos.com/photos/member-galleries/p44529-rad-bracket.html
I noticed this bottom rad cushion bracket is not placed properly and its going to wear a hold in my rad. I've loosened the top retaining bracket off, but while the bracket will flex a bit, I can't get it to move over into position.
Can anyone confirm if this bracket is welded in place? or do I need to exert more force to move it?
thanks

Bruce,
The bracket, and its quads on the other side and top, is spot welded in
place; you aren't likely to move it with the radiator installed. IIRC,
Gene's instructions for installation of the AL radiator calls for removal
of one pair, top & bottom. When installing Rob's, and mine, I think we had
to remove two of them to get proper alignment of the rubber isolators.
If you haven't already done so, this would be a good time to make the
bottom 6" of the lower radiator support removable for future use. I'm sure
you've seen the photos of how others have done it.

I did mine 4 years ago so by memory, the top core support come off with 4 bolts. Then the U shaped cradle that is sides and bottom had 3 bolts on each side and then the whole thing drops down. Did mine that way. Used a floor jack on the assy to lift and line up the bolt holes to hand start.

Ken,
You're correct.
There are four of the alignment brackets in the radiator frame, two top and
two bottom.
The radiator instructions note:
Quote:
The passenger side bottom metal piece that holds the rubber pads should be
removed by knocking it loose with a cold chisel or bending the tabs down.
The new passenger side pad needs to be moved closer to the passenger side
frame due to making the core wider. You should glue the cushion to the
radiator at the junction of the core and tank.
Unquote:
Being the anally retentive perfectionist that I am we knocked the bottom and
top one off on the passenger side, moved them to the correct location; and
pop riveted them back in using stainless steel pop rivets.
The bottom one was a piece of cake as the radiator frame on Double Trouble
was cut and bolts on. The top was a bit more difficult as we had to reach in
and knock it off. IIRC we wound up using a pneumatic chisel.
Regards,
Rob M.

When I tried to chisel the brackets out of mine, the bracket began to twist out of shape. So I drilled them. Obviously it's important to remove the radiator before drilling.

Jp,
Thanks for the "aide memoire." Now that you mention it I recall that the upper bracket didn't fit.
No smart comments, it was 2 years ago!

I followed the instructions and removed the pass. side bracket from the top plate of the radiator frame. There wasn't enough room
to move the bracket into the correct position because the surface of the plate drops down where the new mount position is. Which
gave me an extra bracket to replace the severely rusted one on the bottom.
