[DML] Re: Modified Trailing Arms For 1/2" Bolts

["content22207" <brobertson@xxxxxxxxxxxx>]

Clarification: 1/64" was the total amount of material removed, not per side. Each side was reduced ~.008".

A 31/64 drill bit barely scrapes the sides of the sleeves. Basically all it does is clean them up. OEM diameter thus appears to be ~12.3mm. 1/2" is 12.7mm.

I also am going to try to find fractional Inconel 718's (same material as Toby's bolts). Whatever gets installed will have proper hex heads rather than socket heads (Grade 9 heads are much taller than standard heads, about the same size as a nut). It's easier to find zinc or cadmium plated 1/2" bolts in TAB lengths than 12mm. And they're less expensive too (TAB length Grade 9's are about $7 per bolt).
