Definitely want to flush out old coolant, run a few changes of water through until all is out. Some OAT coolants can attack the rubber gaskets. An OEM reccomend coolant will be compatible with the materials and sealants. If you are ever unsure about mixing, just don't. Two different formulas can create sludge and clog your whole system. See "Dex-Cool sludge". There is a European blue formula that is glycol based, I believe. It may be worth considering.

Please share your pedal box width at the pedal position. I'm curious if it's any different from my 95 Live axle LC. I realize it's not an easy task to measure that space.

Yep. Hair control. Have hair bands available for the gals. And ear plugs. New unused ear plugs.

How long have you had the 7 itch? It took me 30 years to scratch mine.

Howdy. Do you have a 7 yet?

Torch over the painting surfaces to burn off any oily residues before paint. Things are only original once. Paint what you like. I'm partial to a fire engine red..transmission, nobody will see it. A light grey to see leaks easily is practical. I've been considering painting my lump a Lycoming grey. No tractor colors please.

Sweet Crossflow!

You need Tony's book. It has a good section on the S4 Lotus Seven: Preparation, Restoration and Maintenance. https://a.co/d/0435vmH0 Also see simplesevens.org https://www.simplesevens.org/

Thanks to Dan, it looks like we know the original supplier of silencers for the S2, or something very close. "G.N. Silencer".

Very Chapmanesque https://www.blipshift.com/products/factory-knows-best?variant=41743538192429

Click on the ALL button, then the Load More buttons at the bottom. I see them at the bottom on the third page. There could be more, I just didn't look.

Can we have a link? I go there, and find everything but these. Then there are other sales outlets offering these designs that aren't on an available for three minutes then gone forever basis. Not liking BS's sales strategy. He has about 5 designs for a car that has a 70 year history and isn't slowing down. The 7 deserves its own sticky portal on his site, along with some other icons. It works for him. Nor for me.

What are the particulars? PCD? Rim diameter? Width? Offset? Back space? You would be very disappointed to buy a rim to find the calipers dont clear.

There is a cover called a shower cap. It covers more area than a tonneau. https://www.softbitsshop.co.uk/showercap-439-p.asp

Yes, it's the shape I put my hand on with my father's hand over mine learning to shift. I'm rather sentimental about putting the same transmission in my 7.

I'm looking for a standard 5 spd Sierra / XR4Ti shift knob.

There have been many examples of 7 skins eroding at the frame rails. It took several decades. Im not going to insist thst any of us will see our Cats falling apart during our ownerships, but these things are just good practices whenever aluminum is attached to steel and a current is introduced. These cars tend to sit for months, years. Just disconnect the battery for storage. Especially for the coolant and pump. Aluminum pumps can corrode because the coolant is a conductor.

These 7s built like aircraft and aluminum boats. Actually, they're built worse than planes and boats. There is very little built-in corrosion abatement. They are susceptible to electrolysys and corrosion . For long term care, and to ensure you're not chasing down electrical problems in a few years, understand why battery isolation, when not using the car, is a good practice. https://www.twi-global.com/technical-knowledge/faqs/faq-what-is-galvanic-corrosion-and-how-can-it-be-avoided

AGM has specific maintenance cycle requirements. Most smart chargers (should) have that function. https://lifelinebatteries.com/blog/4-effective-ways-to-maintain-your-agm-battery-and-keep-it-durable/

Hay! That's not Jimmy!

Know what kind of battery you have. If it's an AGM type, not MUST use an AGM charger or one with an AGM function. Use the correct charger for the battery you have. The days of lead acid battery and one charger are over. A good smart charger is the NOCO Genius series. Next, if a battery becomes fully discharged, you can't simply jump it and run. It needs a full deep charge. Have a battery cut-off installed to fully isolate the battery from everything except a charger. Since you have an engine with electronic management, you might have some memory power requirements to consider with a cut-off installation. For me personally, I would install a 12V accessory port under the scuttle for a charging port. It can double as accessory power if needed.

For balance it shouldn't matter much. For measuring volume, restrictions might have to be adjusted for, if they aren't already.

Ok, which gauge do you like?

Comments on the RX-7 axle by Graham "First Gen Mazda RX7. Great little axle, if you get the one from the GSL-SE you get disk brakes and a LSD. The 4.076 ratio is just about perfect for a 7, giving a good top speed in you 1:1 gear. It is strong and very light."
