Make sure it is a "power back flush", and there are souring agents and chemical 
scale
loosener which may still be legal in England .

Brass, with flared ends, of course.

Need to make new horn lower flat bracket about 1 inch longer, or add an 
extension, to
go through fabricated aluminum flat plate.  Double sided tape can hold it in 
place.
Grommet hole for horn wires.  And any non-original pathways.  Although this is 
just
frosting, not cake.

Probably 170 to 180, if gauge is correct.

AHA!!!!.

Rick, you should be seeing about 14 of those little buggers per inch, and 3 to 
four
rows of closely spaced copper tubes.  This is NOT a high efficiency radiator.

My previous posting listed this as the one I am using:

"7)      Replaced original, or older design 4 row, with new high density, high
performance radiator.  Same thickness as original 3 row, and
requires no mods of tanks.  Modine H 69 H Cross flow.  18 1/2 W x 15 1/2
 high.  Four parallel rows of tubes, 36 tubes/row, each  3/8 inch deep by
0.080 wide externally.  14 fins/per inch fin density.  This is about
$300, built by radiator shop, and well worth it."


Hope this provides additional clarifications.

Steve
