78 Axel Indentification

Just bought a 78 Subercab. Axel code on the door says B4 something. The next mark is either an I or a 1. If it says B4I does that make sense? or does B41 look right? I would like to know what my front and rear axels are and the gear ratios. Also, can this truck be both a trailer special and camper special? It has both the emblems on the truck. Your help is much appreciated.

Axle code is probably? a B4 which is a Dana 60 Limited Slip 5300 lb axle with a 4:10 ratio. The I or 1 might actually be a J which indicates power steering.

Mil1ion actually has all this info on his webpage for deciphering truck rating plates.

Defenitely not a J. I'm pretty sure that it is an "I". So it would read B4I. There no R or N. Thanks.

B4 is a 4.10 Limited sip dana 60

I means it has Power steering and an adjustable steering column (tilt) on 4500 lb front axle.

My mistake, the "I" indicates a power steering, tilt column with a 3800 D60 front axle.
