i rescently purchased the rear disc set up from bill harper(navy lifer)...for those thats done this already... did you put threadlocker on the nut and bolts that mount the backing plates...i plan on finishing it up tomorrow... let me know guys
i am doing the stealth bolt mod as well...as for the metering mod... i think ill wait a couple weeks till i go to the junk yard to get a couple of those bolts(just in case i mess one up)...so i can modify it first...
If I remember from doing mine I think the factory bolts have threadlock on them (blue?). If yours don't it would be a good idea but like Eddie said I probably wouldn't take them apart if they were already torqued down. When I did mine I did the stealth bolt and metering rod mods all at once. This thread https://impalassforum.com/cgi-bin/ult...;f=23;t=001099 has two very good pictures in a reply by Joe Palmer of the metering rod before and after the mod. Good luck.
YES!!! The best practice is to use the correct GM bolts for this with the blue threadlock already there. There are documented cases of these bolts backing out and causing great havoc when not installed properly.
