There is a nipple on the back of the manifold , or 2 , I think you have to pop off the end of it if the donor truck had hydraboost

Not sure if donor had hydro or not. It does have an opening for booster I think...measures 7/8". Been trying to find a T fitting ...no luck yet.

Re: 69 c10 ls/th350
My 6.0 LQ4 donor did not have a booster as it had hydro boost. However the vacuum was on the back of the manifold but it had a plug in it. Pulled out the plug and used a vacuum hose off a 1500 truck that had a vacuum booster.
As far as the TH350 modulator, I connected to a nipple on the manifold on the passenger side. It was capped as well but I just cut off the cap. transmission shifts as it should.
