Hey gang,

Time to start work on this one now! Got a tedious vacuum leak going on.. revs shoot up 250-300rpm every time coming off the brakes, pump the brakes a few times and you're at 1,500rpm instead of idle! I've yet to run a smoke test but will eventually just to check the whole system (i hear my vents operate on that test so i think the rest of the system's fine?).

Also looking at the condition of the thing on what must be an original part plus damage brake fluid's done to that whole corner of the car over the years! I think it's busted.

I see two on NPD of which only one fits a 2.3 model and excludes convertibles and I see two on CJPony one for just 2.3 and one for 2.3 and 5.0 alike in a much fatter style, I believe this larger sort of a style booster is what's on the car and neither of the CJPony listings mention convertibles at all.

So I wasn't aware there was anything fundamentally changed on this part for convertibles?
Interested to hear if you have any information on that one too!
Seemed like something worth checking out in light of the NPD listing.

I'm fairly certain that the booster from the first CJ link is the same kind? What do you think?

The convertibles used the same booster as the 5.0, which is what your photos are of. The convertibles were heavier, so they needed a little extra help stopping.

You can get the same Cardone booster from Rockauto. Even with shipping and not returning the core, it's cheaper than CJ's. I would also check your local parts store and see if they cardones. Cardone is pretty much one of the only reman houses doing boosters for these cars so it shoul;d be easy to track down.

Ah cool! I'll grab it from there, thanks! Rockauto's site is much nicer to navigate as well.

Interesting to know the tidbit of the full fat booster for the fat assed verts!
