Did any of the Gen1 Rams come with the hydraulic power brake booster called a Hydrobooster?

I'm looking into a project for a friend, who has a 1991 3/4 diesel 5 spd.

The truck currently has a vacuum booster and he wants to change up to a Hydrobooster. I know they were available in the Gen2 and Gen3 Rams, but if the Gen1 had the option I think it would be a much easier swap.

Thanks.

 

Might look for a 12v hydroboost. I don't think they could be much different.

 

I was mainly concerned with the firewall pattern. I don't have a way to check the firewall bolt pattern without removing the booster to cross check it with Hydrobooster options, and being a daily driver that would take his truck down for too long.

My thinking was that if a Hydrobooster was a factory option in 1991 the firewall patterns between Hydroboosters and vacuum boosters would be the same.

 

Not a 1st gen, but I found this thread on CF:

Apparently the 1st and 2nd gen trucks didn't have hydroboost and that was something that was offered on 3rd gens.

 

I think the Gen2 trucks did have the option, as I have found some from various years ranging from 1998 and 2001.

If I could get his booster out then at least I could get the Hydroboosters that I am used to working with mocked up with the bolt pattern and pedal rod length, but he just can't afford to be without the truck for even a few days.

Do you happen to have a spare Gen1 Ram booster that you could take some pics and measurements from?
