[Tigers] bumper over-riders

[Rollright at aol.com]

Hello,
 
I got a set of bumpers chromed recently, and now am addressing the  
over-riders
 
In the Alpine parts list there are two listed:
2226483 and 5115347   and from the outside they look  identical.
 
The 2226483 seems to be an over-rider with slightly thicker steel and an  
internal brace brazed inside. The brace has a bolt hole which is  threaded 
for the fixing bolt.
 
5115347 has thinner steel, no internal bracing, and a carriage bolt hole to 
 stop the fixing bolt (carriage) from turning.
 
I have a Mk 1A with the latter type and am tempted to switch to the  old 
(seeming all around better) type. Further, I don't know if  any Tigers came 
with early type.
 
Anybody have an inside line on this issue?
 
Jim Armstrong
