Power Steering Pump Upgrades/Coolers

Now I am not sure what I have. I replaced the MC about 3 years ago and I honestly don't remember if I ordered a Chevy or Ford MC. I will measure bolt spacing in the morning.

I have photos but for some reason I can not upload with Tapatalk.

Not sure when Dodge went to Hydroboost but my 93 is vacuum assist.

Dodge converted their diesel trucks to h-boost in '97 or '98 as memory serves. My buddy with a '96 on our Nevada expedition last week is also vacuum boosted. I've helped him round up all the parts to do the conversion on his.

Ford started h-boost in the early '90s on the Super Duty trucks when they were a separate model from the F250/F350 trucks. The F250s/F350s got h-boost in '99 when the new trucks were introduced.

As Paul noted, GM started using it first - back in '73 or '74 on heavy duty light trucks (1 tons and such).

My 96 dodge CTD is vac assist.

Anyone got more info on the firewall pattern? Rod lengths? All my projects have to be in and out the same day so I need as much info as possible before teardown
