    Hello, well the starter is acting up on my ‘70 GS 455. Once in a while the starter is dead but everything else works, lights, stereo etc. I can tap lightly on starter with hammer the it will start. I’m ready to ready to replace both starter and solenoid, does anyone have a part number for the replacement starter. Dealer told me there books don’t back to that year.

    My son used a NAPA starter (New, not rebuilt) in his 72 GS 455.

    It was about $80

    Works great.

    Don't toss or use that OEM starter as a core.

    Stellar here on the board rebuilds them. They're very hard to come by these days.

    You need to check the numbers on your starter, it may or may not be worth saving.

    If time allows I may pull the starter off today and look it over.

    I think the disc inside solenoid has a few burn spots on it. When i was a kid we would take them apart wire wheel them and it was good to go. The tap with hammer was always a go to to fire them up. Ha

    Ive used some fine sand paper more than once to clean the discs. They are supposed to rattle/turn with use to catch a clean spot. Even so, a new solenoid is less than 10.00. I'd replace with a reman. Make sure its a 455 and not a 350 starter. ws

    The 1970 stock starter is 1108392. Not unusual that a 50 year old car has had the starter changed out one or more times.

    Your 1108430 is a BBO (big block Olds), or BBC (Chevy) starter. It's a good, heavy duty, high torque starter and was used on 'vettes and stuff like that. You should try to fix it or get it fixed.

    Thank you all for the information. Hopefully one day I’ll be able to help back, still in the learning curve. My first car was a Stage 1 but I was 17 years old and all I knew was go fast. Thanks again.
    I kept it and didn’t turn in as a core. I think the problem was the solenoid. I definitely keep and have tested after good inspection and solenoid replaced.

    Hmmm...I don't know Bill. For Pops, there is one thing you need to know. The original GS starter had a threaded hole for a support bracket. Because the 1108430 was used in Chevy aps, it probably doesn't have that hole, but rather has a longer case stud for a bracket.
    I did find some info for you Bill, but tooth stuff I don't know. Like you, I know when they rebuild stuff, they just put the parts on to do what they need. It seems it's something about the staggered mounting bolts has a relationship to the tooth count? Maybe they just change the nose or starter drive? Take a look at this...

    Im not too sure either.. my cardone unit came with the bracket hole and longer case. The OEM bracket still show some 1964 Buick puke green from the fireball V6.
    I was naive about it then but now I know LOL... Some rebuilders also put a rubber "rivet" in that hole to keep the water out. ws

    I’m saving my old starter to put a new solenoid on. It didn’t have the support bracket on it. The rebuilt one did have the stud about a inch kind out the end. But when installing I didn’t see any place on block to attach a bracket. I don’t have one, will have to search online to see if I can locate one.
