While restoring the 69 Z I replaced the motor mounts with units from Year One. After sending back the 69 Z mounts and calling the tech line/service
I was told some of the early cars had 68 Z/BB mounts, maybe until newer version release or supply was used up? Can any of you early 69 guys confirm? My 69 is a 68 built 10E car. Anyhow I have looked at the mounts a few times and
wonder why 68 style? The 68's are wider tower with engine mount containing spacers welded on right? I seem to remember the 69 style motor mount being too narrow to fit the wider 68 style tower? Also I'm pretty darn sure these towers are original, they looked like the original hardware had not been removed when I pulled the engine out.
Next question; Do the modern style engine mounts I purchased contain a built in rubber isolater stop-lift fastening device?
By this I'm talking about the engine lift brackets I see on e-pay all the time. Seems in the first gen cars the mounts would break loose
and the accelerator would fully engage with disasterous results.
I'm pretty sure some of the newer design non-original mounts I've seen have a metal tab retainer built in them to provide break-away engine retainment.
Do the newer original style mounts incorporate a fastening device engineered through them to prevent this problem right?
Why is everyone insistant on providing stop-lift brackets on a restored car? Is it for motor mount retainment on original restored cars?
I'm a little worried if mine might not come loose at some point. If they aren't for retainment then why?
If these parts would be correct then why shouldn't every TSB part be installed for us anal-retentive correct guys?
Was this a major recall or just a TSB.
