Coupe GT seats and tick/clatter

[Hammand@aol.com]

I'm new to the list, having just bought an 85 coupe gt. I am trying to find a
source for replacement (- used ,GC) front seats (in blue/ cloth or dark
leather). What VW, Audi models will seats fit the coupe (GTI,Scirocco, later
coupe models)? 
Anybody have a parts car with a good set for sale?

  Additionally, the engine has an occasional tick/clatter (not valvetrain
noise). Has anybody had luck eliminating a similar noise ?  Oil pressure check
valve ? Car has plenty of power , good oil pressure (3-5 bar on guage) ,and
burns no oil but LOTS of miles (200K+).
 Any suggestions or help  would be greatly appreciated.
