[oletrucks] Rear end Ratio on '54 3100 (3.90 or 4.10??)

[BDober@aol.com]

Been thinking about the new pinion kit to improve speed now that the 235's 
head's been rebuilt. Question is I've heard that the 1954 AD's had a 3.90 
rear in them, anybody know that for fact. Would seem like alot of bucks just 
to go from 3.90 to 3.55, actually its alot of money to go from anything to 
3.55. Anybody out there know if these last line of AD's had an improved ratio?
