Unless you are absolutely sure the distributor has never been tampered 
with, rebuild or modified, you cannot go by the numbers. All 25D 
distributors bodies were the same with variations in advance springs, 
weights, advance /retard vacuum system, 4 or 6 cilinder top shaft plus 
some variations in the drive system, off-set dog, gear etc.
When rebuilding distributors one takes an empty undamaged body, with any 
numbers stamped on it, and build it up according the needs for the 
specific vehicle with the specified parts. Some re-builders may mark the 
body as modified/rebuilt for a specific application, but most probably 
will not. In the past I have rebuild many distributor this way and I 
must admit I never marked the bodies to be identified in the far future.
