327 396 427 Starter Bolts
Permalink  

Many of you may know that our 60's GM's had some special starter bolts for the starters that had a cast iron nose. I believe this nose was used exclusively on big blocks and/or small blocks with the 11" clutch (168 tooth flywheel) The original GM number is 3733289 for this bolt and it's not just a plain 3/8" X 3 3/4" bolt, it has a special knurled section where it fits into the block. 

I am looking for a pair of these bolts and all I can find is some grossly overpriced OEM bolts on ebay or these Dorman bolts on Amazon.ca 

https://www.amazon.ca/Dorman-678-005-Starter-Bolt-Box/dp/B0033YHEFE

The ones on Amazon.ca are fine but it's a box of 10. If  have to I may buy a box but it seems like a lot of money to spend for 2 bolts! Is anyone interested in sharing a purchase of these? I would take a couple of pairs but I sure don't need 10 of them!

NAPA?

They have some that look like that, different head style, so may have a different part number?

Ive seen some of varying sizes at Canadian Tire.

The place that rebuilt the starter for my 4 speed provided the cast iron nose. They also had to bring in the bolts, so I brought in a spare pair. They got them from Shaw GMC, don't recall what I paid for them.

 It's the length of them Dave. No other GM starter uses the same length as the cast iron nose starter uses. It's 3 5/8".

 GM discontinued them a few years ago, sadly. No dealers have any in stock either.

 Thanks for the tip. I know AutoValue (Piston Ring) doesn't have them but I didn't try NAPA.

The Dorman ones are available ea. under p/n 678-005.1 vs 678-005 for the 10pk. I'm not sure where you can buy them though. www.dormanproducts.com/p-20399-678-0051.aspx
Actually, I take that back, it looks like you can order singles or ten packs from Rock Auto: www.rockauto.com/en/parts/dorman,678005,starter+bolt,4153

If you want to spend more money, AMK has them too: www.amkproducts.com/bulk-fasteners-products/

I called a couple parts stores today looking for the Dorman 678-005 bolts to no avail. However one looked on the display and found Dorman 45657 to be correct 3-5/8" long. It's readily available, should be $5-6 each.

Interesting. That looks correct. However, I went to the Dorman site, punched in starter bolt and there's a nice list of starter bolts but that number isn't in there. Then, if you scroll down past the bolts, there's alternator bolts, ignition switches etc and then more starter bolts! 45657 is in there.

Oh well, I have some ordered from NAPA anyway!

 I had asked for the NAPA part #, but then saw it was displayed.  I was trying to delete my post from my phone, but it said I didn't have permission.   So I edited it to just be one letter.   Now that I'm home I could delete the post.

LOL, I thought maybe you'd spent too much time at the bar on the way home from work!

 Interesting. The photos look identical on the Dorman site, and if you check the Rock Auto link it does show that as an alternate part number. So it seems they're identical. Might just be different p/n for different packaging? 45657 says "card", and 678-005.1 says bag.
