misterc9 Posted July 27, 2021 Share Posted July 27, 2021 (edited) Does anyone know where i can get a rebuilt brake booster for a 73 grand am with a 400 engine 6.6 L. It's a Delco Moraine unit. The listings I have say it has to not be a wagon and not a 455 V8. It also fits a few other GM intermediates 73 to 75. It doesn't fit all of any one model and is limited to certain engines and body styles. I have the original GM part # 2620599. ( i think) None of the rebuilders I have talked to have a core to rebuild. GrandAm is included in LeMans listings.

misterc9 Posted August 19, 2021 Author Share Posted August 19, 2021 (edited) Thanks to all for the recommendations. Dewey has a five week turnaround but was cheaper. Harmon has two weeks. It's at Harmons now. Hoping to be back on the road before summer is over. Edited August 19, 2021 by misterc9 (see edit history) Link to comment Share on other sites More sharing options...
misterc9 Posted September 8, 2021 Author Share Posted September 8, 2021 Got the booster back from Harmons in less than two weeks. Back together and on the road all is well. 1 Link to comment Share on other sites More sharing options...
