Need seat

Hi Im new to forum so I hope I get this right. I am restoring a 79 z500 the seat is
fairly tatty although I think I could still use the pan.I have been offered a z400 seat
Will it fit my z500 If not could some one recommend a souce for a cover for my seat

This is a great forum thank you all

Try a local car upholstery shop. They are starving for work right now. They did a great job on my seat. There are places you can send the seat to get it covered but that's a PITA and probably costs just as much.
