Maybe ask Jeff (88IntegraLS). I know that he has used the Teflon Encapsulated seals before, but I don't remember if he used the Mcmaster ones or the RA ones. I believe that he went back to using Mazda ones though, but I am not sure. I know that the Mazda ones are expensive. You can almost buy a whole gasket set for what just the coolant seals cost. Why are you having trouble with the McMaster seal? Do you not have the part number, or is it that you can't find them in the catalog?

I'm actually looking for mcmaster seals for a early 13B 4 port... talked to atkins this morning they said that there not the same size as later 2nd gen seals. they are the same size as 12A seals.. so so no go on mcmaster inner seals that are cheap... due to size diff... it looks like I'm going to have to measure the groove and search mcmaster site for right size... I never really wanted factory inner seals, but not really getting much of a choice....

dude that would be sweet gonna measure tomarrow.... the thing is I talked to a friend of mine that has been in this biz for quite sometime he says its a no go mcmaster doesn't carry that size... well see I might just cut a splice at proper side.. use extra hylomar... or i'm thinking of using teflon encapsulated 18 guage wire... just might try it......

Okay,
I get about 0.1285" or so as the width of the groove and about 72.2 cm = 28.425" as the circumference. This means the diameter should be 28.425/3.14159 = 9.048". McMaster-Carr has an FEP-Encapsulated o-ring that is 1/8" thickness (fractional) with a 9" i.d. and a 9.25" o.d. This is probably the closest that they have. The actual i.d. is 8.984" and the actual o.d. is 9.262" which gives an actual thickness of 0.139". This should work, although it may be a bit big (may need some extra hylomar to hold it in place). If you need a hand when you rebuild, let me know. I will come down and give you a hand.

Just to give you a little more confidence, it appears the 2nd gen guys are using the -175s which are 9" i.d. and 9 3/16" o.d. So, the only difference appears to be with the thickness of the groove.

I hope those work out for you. If they work, we know that others will be able to use them in 12As and early 13Bs. If you have your housings out, go ahead and measure them just to verify. I am pretty sure on my numbers, but I don't want you to order the wrong part on accident. I would be happy to assist with the rebuild. Just let me know when you need the help. Sounds like a cool car.
