I have a 1970 Oldsmobile 98 that I've been keeping alive for the past several years. I'm looking to replace some of the more worn interior parts, I've found carpets and a headliner, but am looking for seat covers/ new fabric for the front 50/50 bench seat, and the back bench with speaker cut out. It doesn't seem like these are being made en masse, but if anyone knows something that would fit, that would be fantastic.

 

Contact some local upholstery shops and get an estimate to somewhat duplicate the patterns with a material of your choice.

 

Here's a vendor that I ordered aftermarket seat covers from in the past.

It is also worth noting I've found covers for 1970 cutlass, which is certainly close but not exact.

 

The seats are different.

 

Sms auto fabrics can definitely help you with finding material for your 1970 Ninety Eight

 

They can, but it certainly will not be cheap. I paid almost $170/ yard for the correct cloth for my Toronado seats back in 2019.

 

I bet that tornado interior looks great tho. It's not cheap to look great

 

Just spent $700 for material for the front seat alone on my 71 Ninety Eight

 

If you're not concerned with originality and your old seats are in ok condition, use the old covers as patterns and have a shop sew them up, install yourself. Good auto upholstery material is available for about $25/yd. A hogring pliers is about the only tool needed.
I didn't want vinyl, so I sewed and installed my own cloth interior (post #78)
