The diameter of the special cap and housing are 5/8" smaller than stock Ford distributors providing extra room in front of the engine. The new MSD cap features spark plug style terminals and is firmly screwed down to the housing. The distributor relies on MSD's race proven magnetic pickup and precision reluctor to deliver accurate trigger signals to the MSD Ignition throughout high rpm. The reluctor assembly is turned by a hardened steel shaft which rides in a sealed ball bearing for high rpm stability and endurance. Mounted to the top of this shaft is a fully adjustable mechanical advance assembly. The rate at which the chro-moly assembly advances the timing is easily controlled by changing the supplied advance springs and stop bushing for total advance.

Afun way to see Paris as a kid
Format: Paperback
Great way to have kids really look at the sights of Paris. Encourages group or single competition to do each activity. Lots of visual clues.

Great travel book for kids.
Format: Paperback
This book was great, I plan to get one for any other city we visit that they have a book for. Good level info for my 8 year old but also had some fun things for my 4 year old to do. Very flexible so we could just see what we were going to see & work it into the ‘mission’. We would bust it out at our cafe/people watching stops to see what we needed to do at the next stop. The information was fun for kids and adults. You get to set points for a few things so the mission is completely attainable no matter what you do in the city AND you can set points for adventurous things your kiddos might not otherwise do... eg I got my 4 year old to try escargot!

Worth it!
Format: Paperback
Great book to help keep kids engaged and excited to tour through Paris. Recently used it on our trip with 5-8 year olds and had a blast searching for paintings in museums or various sites through the city. Had some interesting facts/history to share about the various places (although wish it had more)

Kept a 10 year old engaged
Format: Paperback
I bought this for my 10 year old for our trip to Paris. It contained some activities that kept him interested during our museum/castle trips. It even lead us to Chateau de Vincennes which we wouldn’t have found on our own! The Louvre hunt had us going all over the place (mainly because he can’t leave anything incomplete) but it helped initiate conversations about history.
The only issue is that the Notre Dame challenge is sadly impossible to complete now based on the fire in April. I also wish something would be added regarding Les Invalides.
If you have elementary aged kids then I would highly recommend.
