[R-390] IERC tube shields for my R-392

[frankshughes at aim.com]

Hi,
I want to replace the silver tube shields in my R-392 with IERC.


I have read all the info I could find (or actually Google could find) in 
an 1998 ER and also some web sites. 


As far as I can tell, the 5015 is 1.5", which covers the majority of the 7 pin "short" tubes in the R-392, and the 6020B covers the medium 9 pin @ 2.5".


Before I buy these things, does anyone know if there are any other variables like ID variations or other tricks to this?


QUAN       IERC P/N
19          5015B
5           6020B
