This is on my 85 XJS V12, I am getting the car in show quality shape, all it needs now is the interior redone as the car looks AWESOME. When I bought it earlier this year, the pair of JAGs were from an estate sale with an 86 XJS V12 too and I have so many parts and extra V12 motors. Found a TON of NOS genuine JAG parts in boxes-the lot is crazy and some is from 1970 series JAGS up to the XJS line. The 86 XJS V12 is beautiful and hell I am not into JAGs but this car is REALLY gorgeous but had 2 different PS leaks and both were pretty bad leaks. The one was a simple leak but this other gasket I need to buy. This is a pretty big gasket into the rack where the knuckle meets the rack and anyhow that is where the leak is and I sure do not want too buy a rack for a simple gasket. Anyhow have the part # for this so I can order one? Thank you and anyone looking to buy my entire package of JAGS and parts, please call me 856-300-5138 and Happy New Year! Gary

 

There is a large heat shield on the pinion top and a seal under that.
