how long were the engine hold downs used? when did they begin and when did they end?

thanks

I bought a 68 RS four years ago from the original owner and it had the driver's side hold down cable still on it. He gave me the original paperwork which was the actual recall notice dated 1973. This is when he took the car in to have the hold down installed. Not sure when installations started and ended it but I know for sure it was going on in 1973. My 69 pace car still has the hold down too but no idea when it was installed.

A 69 350/396 Camaro should not have it. Only 307/327.

All '69 302/350s & bbs used the interlock mount which will not separate if the bond fails.

Are u talking about the wire rope with the eyes in the end?
I still have the orginal that came with our 69

yes steptoe, that is the one im talking about. so a 350 will not have one then, right?

What about 67/68?
I remember pulling those off some scrapped 1968 350 Impalas and Chevelles.
Did the Camaro 350 get it in 68?
I also remember seeing them on survivor 1967 SS-350's

Either way, if you are going for a "Factory Delivered" restoration, those would not be correct, because they were added later. Right?

My 1969 survivor L34 was recalled for the motor mount breakage problem, and has the safety cables installed. I will check, but I don't believe my car has the interlocking motor mount. BTW car was built 9B of 68. This was the only time my car was back at the orig dealer for service.

My buddy bought a 350 z11 in the late 80s that had one on it.

Yes it did have one ex factory (350)...not a recall...
Not long after it was sold new in Ca it was shipped to NZ...
Camaros where not built in NZ as they where lhd and not factory convertable to rhd
Its my understanding the recall was early 69 something about an accerator getting stuck, and shooting into a Mall killing ppl in 68
I remember reading about it yrs ago....went something like that anyway...

I know I had a low mile Burgundy Z28 with window sticker and it also had a registered letter for the motor mount problem. The vin of the car was on the letter and showed thru a window in the envelope.

That's interesting.

302/350 and big-block frame brackets were specifically re-designed for 1969 to accomodate the new interlock motor mount which is narrower and thicker than the early style mount. Chevy continued to use the 67-68 bracket and mount with 307 & 327 engines. John De Lorean claimed the mount design as his own and spoke of it in his book.

The recall cable will serve no purpose with the interlock mount as it can't separate.

Sounds like the General wasted a lot of money recalling cars that did not need it.

The earliest recall paperwork I have is dated 1971.

If u look back to that time, the corvar/nader affair was still very polically influentual...Companies had to be seen to be proactive....be it needed or not.
So a freak accident, and injuries (think there was a death to??) GM acted quick, regardless if it was a real issue or not.
Add other political issues at the time of fuel costs, insurance and safety issues with muscles cars...
Wasted money...I dont think so...if weighed up against deneighing it was a problem, bad publicity, lost of sales..and the cost of recall and adding to production line...by far the cheapest option.

Edit:
Althu the recall as far as I understand was in 1971 or 72 that doesnt mean that the restrants where not added well before this ex factory....for several yrs

I have looked at many original 1969 Z28's and Big Block cars and most had the old style non interlocking mounts (some may have been upgraded over the years). All the survivor cars I have owned have had the non interlocking mounts as well. The cars I have documented this on were built from 9B of 68 to 6A of 69. I did refer to the assembly manual and there is a revision date of 8/9/69 regarding interlocking motor mount. Could this have been the cut in date. Just trying to clarify/identify the use of these mounts.

Anyone out there with original car that can perhaps shed some light on this issue.

My 69 SS396 had the cable, I still have it in my parts stash. I took it off years ago. The car has been in the family since ordered new.
