I think this will be helpful to people to actually see the process and parts hands on to do a hydroboost conversion. Truck is coming together.

Something ain't adding up. Literally and figuratively. The new core support is sitting an inch lower than it should to bolt to the fenders. That should not be happening because I measured the old and new core supports and they are both 19" from mount to top. I'm using the same bushings and hardware. Gonna go eat lunch. What do you think?

I'd bet something is up with the bushings. When I rebuilt the support in my crew cab, I bought new bushings from JC Whitney. I'd guess there was some funny business with the old ones. One of my trucks had hockey pucks for Pete sake, lol.
An inch is a lot to make up, but I don't see any of the oem shims, which would definitely make a difference.
Hope this helps

I haven’t figured out yet how it worked in this configuration previously though, I have pictures with it. Same measurements. I’m familiar with the correct shims but like you said it doesn’t make up an inch.

I was thinking of the body bushings too. Looks like a body lift was done. Maybe have to fab up some spacers to go on the bottom of the rubber bushings.

It’s got a ~4ish suspension lift and no body lift. The body lift was a good idea though. I was seeing if I’m missing something obvious which I must be. Thanks for the replies. I can cut and weld anything to fit, if Nero wasn’t across the country I would have taken the diesel core support just to have another one since it was free. The 460/non AC core support from quickster is the same measurements though it just has a different drop width which I already modified to fit.

Im gonna dig up some old pictures.

This is the AC core support the truck had previously that’s in my post with the 19” measurements and same bushings. Wanted to look back incase there was a spacer that didn’t make it in the bag but nope
