I love when my ultra experienced friends call me out of frustration on a thread like this and say this guy doesn’t know what he is talking about. This is not the first thread where “recarno” makes a blanket statement of “this is wrong and I know better” (without a single explanation or providing any evidence). Telling us to use a search function when you are the one making claims of something being incorrect or different is rather ridiculous, because no one knows what you are talking about.
There used to be the “sport seat police” on this forum. A group of guys that knew about correct sports seats because they had original cars. Unfortunately much of that info was lost when the board was hacked. I was honored when one of the original guys said to me you have earned your way on the force. Having a ton of money invested in sports seats for my own 911S cars I do take this seriously and I base my knowledge on the hundreds of cars and seats I have seen. I started with my first pair of sports seats in 2004 when they were $2500pr. Now there seems to be so many people who base their knowledge on what they have read or what someone told them and the waters are sometimes so muddy. It is true that sports seats are very complex and for this reason there is no reproduction that can fool us that know. Especially when talking vinyl/leather material this is a difficult topic and these materials are NOT AVAILABLE NEW no matter what someone tells you so only a good substitute can be used - which is what we are all trying to do here. Many people who dig out a set of sports seats for the first time from storage or an inheritance have no idea so yes often those claims on a first offered seat can be false, you have to take all this info with a grain of salt.
It’s 2020 and we don’t need to develop film anymore so shooting a picture and posting it is very easy. There is no excuse for not backing up hard headed opinions with pictures, no matter what job or obligations you have in your outside life. Pictures speak 1000 words. For my contribution today here is a genuine 68 sport bucket with original covers and a genuine cover from a 67 sport seat. Then the holy grail - the Jennings million dollar 67 911S which is the most fantastic original car I have ever seen. My pictures and the parts were in my hands. I don’t see that there is a difference in perforations between SWB and LWB. The point is you want a wide hexagonal pattern which none of the big USA upholstery shops are doing (I’m in San Diego half the Porsche trimmer talent in the country is here).
To the seller and buyer of the original seats in this thread - great seats, excellent example, no complaints. Those seats are a wonderful reference for a 69-71ish car.
