TheBMan Posted January 5, 2023 Share Posted January 5, 2023 Hey guys. Does anyone have a photo of the throttle return spring mounting bracket for the 1970 454 LS5 Quadrajet? I need to get one and I'm not sure what I'm looking for exactly. The service manual doesn't help other than an illustration that isn't definitive. A Google image search isn't helpful, either. If anyone has a bracket they would like to sell, PM me! Thanks! Quote Link to comment Share on other sites More sharing options...
1970mcss Posted January 5, 2023 Share Posted January 5, 2023 I can't find a good picture of my carb, but I thought the return spring runs back to the bracket that holds the throttle cable. Something like in the one in the picture (Not a Monte) 1 Quote Link to comment Share on other sites More sharing options...

This is what I have on mine. Mine is actually one of the Edelbrock quadrajet units (1901 I believe), but the basics are the same. 3 Quote Link to comment Share on other sites More sharing options...

DragCat Posted January 6, 2023 Share Posted January 6, 2023 I know I'm late to the party on this, been a long day 🤣 This is what I had when I purchased mine. Quote Link to comment Share on other sites More sharing options...

This confirms the spring type that I thought I need. Quote Link to comment Share on other sites More sharing options...
sbarnette Posted January 6, 2023 Share Posted January 6, 2023 I noticed Michael’s has a spring in front where the throttle cable mounts, but Mark’s does not. Mine has two springs as well, but I have seen others that don’t. Anyone know if GM built them both ways or if they have just been changed over the years? 1 Quote Link to comment Share on other sites More sharing options...

I'd like to set mine up however it was when new. Quote Link to comment Share on other sites More sharing options...

It seems like the double spring (one inside the other) going to the rear bracket is the OE setup. 3 Quote Link to comment Share on other sites More sharing options...

The factory set up is one spring inside the other to the carb and to the bracket that the throttle cable mounts. 2 Quote Link to comment Share on other sites More sharing options...
riverdogs00 Posted January 6, 2023 Share Posted January 6, 2023 I do not know that my spring is original - its just what was on the car when I bought it 6 years ago 2 Quote Link to comment Share on other sites More sharing options...
