90Q removing bolt from rear diff mount.

[Steve Sears]

On the same vein as Louis-Alain's post, could someone verify that the
subframe bolts on a Type 44 are the same stretch bolts as mentioned on the
ur-q?  I replaced the ones on my '87 5ktq recently and noticed that the old
ones were no different than the new ones - same length (old and new,
uninstalled), same uniform thread pitch, etc.  I replaced 3 and kept the 4th
off for comparison.  The Bentley Manual makes no mention of replacing the
S/F bolts on the 1986-88 Type 44.
Cheers!

with OEM.
