In Need of Carpet Replacement

Well I'm definatley going to replace the rust-encoated underlay...after I fix the rust spots. Some people say I shouldn't bother putting the $ into putting in a new underlay, but wouldn't that just make it even noisier inside?

Also, I see a 1986 2-door sprint carpet for sale online...does anyone know if that would be the same fit for a 1989 2-door sprint?:screwy:
I am thinking of selling it in about 6 months, so I don't want to sink a bunch of $ into it, but I do want to care for the poor little thing!

Right on Sprinters...cheers
