69 fj40 front drum specs (1 Viewer)

[Honeycutt]

Hey y'all,

Need some salty old guy wisdom. I took my front drums to get turned at Napa, and they didn't have the spec. I haven't been able to find it either. Does anyone know the spec distance of inside diameter of the drum? I don't know if the drums are too worn. My Napa guys measurements were:
1- metric 291.21.3mm
standard 11.467-70
2- metric 291.2mm
standard 11.463

Any help or clarification on this issue would be appreciated! Thanks for all that commented on my last question!

cheers,

First, you haven't closed the loop on "Tranny mount bolts confusion." Did you resolve this? How did you eventually fix the issue with the two bottom bolts?

Assuming you will go back and close out your tranny bolt issue, here is informatin regarding your brake drums:

From the "1958 - 7/70 Body & Chassis Manual" available here on "Mud in the refereence section:

IMPORTANT NOTE: This specification is for OEM Toyota drums. To the extent your drum match OEM dimensions, it's accurate.

My OEM drums have the maximum limit (293mm) cast into the lip of the drum.
