new member 69 xr7 convertible project

hi there, cougar forum folks, i have now a 69 xr7 convertible(351w with fmx trans),it is now a driver after a 25 year plus slumber with previous owner, so im looking basically for some advice from knowledgablecougar members,.

heres my first question,where is the best place to go for interior bits, new foam,seat skins, my car is now black,upholstery was redone in past,not well,
seats tired,ive looked on npd site,is that a good choice?
, im a bit staggered by the costs of seat skins(having done some 20 plus year ago) but ive already pulled out carpeting ,and am looking at some patching needed under back seat,otherwise floors look pretty good ,former owner said car was bought at carliyle ford show in early 90s,anyway very happy to be cougar motoring again,ive had to replace the entire fuel system but motor seems to work fine,ive done new carb,wiring,etc.but shes a joy to drive and up my way i dont see very many cougars,eastern ontario,canada, cheers folks,look forward to the site
