The instrument cluster assemblies were provided by the vendor directly to the assembly line at Willys/Kaiser factory. For M38A1 up through sn MD70114 clusters ORD # 7418835 supplied by AC PN 1582076 and SW PN 502F. For M38A1's after SN MD70114 the clusters ORD# 8376619 were provided by AC PN 1582890 and SW PN 502Z. Speedos used with these clusters were: ORD#7760396, AC# 1580260 & SW# 503A used with Cluster ORD# 7418835 (These were luminous units) up through MD70114 and Speedos ORD# 8376375 AC# 1582373, SW# 503C & AL# EO-12205 used with cluster ORD# 8376619 (after MD70114), 7954878 (Early M170) & 7954879 (Late M170) (these were non-luminous units).

MD70114 would be about JAN 1954.

MSXXXXX would have started showing up in the mid to late 60's but they would still have the AC, AL, SW numbers on the bottom edge of the face.

In your case I would look for a Non-luminous speedo bearing one of these numbers: ORD# 8376375 AC# 1582373, SW# 503C & AL# EO-12205
