Help with Ford shock absorber part numbers

[bullrunmotor]

I'm trying to replace 2 Ford rear shock absorbers from the 50's -60's. they are on a old street rod with modified rear axle set up so "year/application' chart wont work. One is marked:
Autolite
AJ 18U 60B
REAR

The other is marked"
4146429

Bot have Ford Script Logos on them. does anyone know of a guide where I can refer to closed and extended sizes/dimensions should I not be able to reference these part numbers? Thanks in advance
