Does anybody know if there are other bench seats that will directly slide into a 91? Like from a Silverado or ford?

 

Nothing will directly bolt in.

But if you have a welder, sawzall and some fab skills anything will fit. I'm a big fan of the pre-side curtain airbag Ram seats.

 

Any '72-'93 Dodge truck bench seat will work.

 

I put ramcharger buckets/console in my clubcab. Best seats it's ever had.

 

I agree those are great seats in a Ramcharger or club cab. Since he lists a ‘91 and they did not offer the club cab with the diesel until ‘92, it is safe to guess he has a regular cab.
I find the high back bucket seats uncomfortable in a regular cab as I can not get enough backward lean to be comfortable. I am over 6 ft so it might work better for a shorter guy.

 

Fwiw, there were '91.5 clubcab intercooled diesels. I have the registration from one I wrecked-out here somewhere.

 

I do not think I have owned a 91.5 club cab Cummins powered Dodge but I would not be surprised if they made one, as ‘91 was a major change over year.
’91.5 is my least favorite Cummins 1st gen to own / work on, with all the crazy change over stuff and 6 month only parts used like PCMs and wiring.

Lets just say there is a reason why I see the bucket seats in the club cabs and Ramcharger…it is because of they do not leave a lot of room for adjustment in a regular cab.

 

Similar can be said of the 94-02 Dodge deluxe bench in the 93-older std cab truck. It's a physically large seat and takes away legroom.

 

I agree 100%.
The 2nd gen 40/20/40 seats in a pre '94 reg cab are not comfortable for me.
