Blair, My 1953-1974 parts book says: 66-67 corvette (427) (except H.D. 4-speed) and 68-69 corvette (427) brace is number 3864972 . But it also lists 67-69 corvete (427) (exc. H/per., H.D. 4-spd.) brace 3932398 . May be someone more familiar can sort this out for you, Lou.

Would anybody be able to post a pic of this brace installed on the starter of a big block with a TH400. Just curious what this looks like installed. Thanks in advance. BK3

Looks to me like installation is the same as regular production. UPC 6 Sheet B 2. UPC L 36 Sheet A 5 shows the same brace, but a different heat shield for the big blocks.
Type of transmission appears to make no difference. M40 section does not show anything different.

Good morning, Mike. Thanks for pointing that out to me. I went thru the AIM countless times and missed both pages. Still some what confused. Looks like 2 different style braces. Here's what I have:
OR is this one correct:
Is one for big block/small block or auto/manual trans??? Thanks again for your help. Much appreciated.

I find it hard to believe that the multitude of '68 owners on this forum have yet to come to your aid, bkvette3.
But mention that the '68 model year Vette was the biggest piece of crap to come off a GM production line during the 60's decade and responses defending their darling would go on for pages. Go figure?

BK. The lower, longer one looks correct to me. The first one appears to be a GM service part replacement.

I looked up Group 2.042 3965588 in the Part List and Illustration Catalog, Corvette, 1953 - 1982. It comes up as a starter brace for 70-74 454.

The search goes on for the correct brace.Regards, BK3

Blair, The above post shows that 3965588 is wrong ( 70-74 454). 3866768 is wrong for a T.H. The above post is incorrect about 3965589. My 53-74 parts book lists it as for 70-72 350 (exc. HD 4-spd) , 73-74 350 , not for a 427. The newer number 354353 is wrong for a 427 T.H. That leaves you with the two numbers that I gave you in post # 2. I do not know why there are two different braces. I am sorry, I have a 327, now 350. Paragon corvette is only showing one BB brace # 1441 and they make it. I would use your part # 3932398. Lou.

BTW: Part numbers changed over the years, service parts. My manual is a 1982 edition, part numbers may have changed from the 1974 edition mentioned by another. If you're interested in absolute originality, your best bet is an AIM. A year or two after production, who knows what substitutions were made for service?
If it doesn't show in the AIM, best you can do is go by the part numbers showing in the parts manuals. It's possible the 1974 edition may be closer to original though the 1982 edition is certainly not wrong so far as functional parts are concerned, probably service parts.

As you do many, many times. Not only about the quirky '68 models but C3's in general.
I said what I said as a means to bring this thread up to the top of the forum because I thought it deserved more exposure. I could have just as well typed BTT. But I decided to spur more responses by using invective. And that still didn't lure more '68 owners out of the woodwork with well reasoned answers to the OP's starter bracket question.
My only help is posting this page from my '73 edition of the P&A 30b; he can pick which one he thinks is correct:

I have no idea where folks get them nowadays.
I got all mine from a very cooperative Chevy parts manager who was to throw them out when the new ones arrived but gave them to me instead. I did all the part number scrounging for my parts orders...he gave me wholesale discount in return.

BBcorv70, I did not mean to offend anyone. I only want to keep the record straight for someone reading this in the future. I assumed chevy goofed in printing the 53-82 copy. The parts books are hugh and to get everything correct has to be a rough job. I would go cross-eyed! I just realized that I have a 53-78 parts book and it shows the 283,327,350 brace #3186511 was changed to #354353. It also shows #3965589 for 70-78 350. I still think that the #3932398 is correct. I bought my parts books over the chevy parts counter. When they went to computers, you could not buy one anymore.

I didn't think I was hallucinating, these books can be tough to read with the footnotes regarding applications. Rather confusing. Over time GM substitutes parts for replacement. If the OP really wants an authentic original part, best bet is to check out an AIM for the original part number. Second option may be to ask a current 68 owner to take a photo of the original part for comparison.

Here's a link to one on eBay...

Many part numbers may have been substituted over the years. You may be better off with an AIM if you want original part numbers. This manual may be of help if you need part numbers for components not shown on the AIM such as internal motor parts, etc.
