First gen Civic (1975) 1.5l 4spd CVCC

[me and my metro]

I really only remember the vacuum line manifold mounted to the firewall. Lots of little steel pipes and solenoids. Yes I remember the three barrel carb with the rich one and the two lean ones.

Yes, I have. It is a great iconic story of how innovative Honda was. The Big Three US could not keep up. Old man Honda was really a giant. And he didn't even want to go to Mars.

ETA 6/24-7/1...

I'll be the vacuum hose schematic on this pre-electronics Honda is a sight!

The holes in the drum measure ~11.64 mm. Too big for M10's unless the knurl is alot larger than the threads.

I would spend the $1.50 each and buy several sizes.

11.64mm is a very familiar sounding size
(m8) expansion bolts go in that size
for example
so I wouldn’t discount anything .

If it were me, this would be my approach I would try first, before drilling. I can always try drilling as a last resort. The studs are cheaper than new drums.

I don't see how expansion bolts are relevant. They use a collar for the expansion part so the OD is larger.

I've checked many places online and unless the information they list is wrong then I don't see the point in physically checking the available wheel studs. It seems like a waste of time. The Dorman catalog only lists one wheel stud in the M10 size and the knurls are too small. The only place I saw one that 'might' have fit was on amazon where the reviews were claiming the knurl was too large and wouldn't fit in the OE application (side x side I think it was). It was only listed at 11mm anyways.

I ordered the bit set. Its gonna be a bit before I get them so I will probably see if NAPA has a book of wheel studs I can look through to double check. I've only seen Dorman wheel studs around here though.

The vacuum lines look like a nightmare and a half. Hopefully its simple enough that it just takes time and attention to get it done.

Note that it's for a 1985 Civic. Your CVCC should be much less complex.

Yea, I saw that. I can only hope right now.

Obviously, I didn't see that when I commented. Looking forward to your progress.

Tried the super chrome. It's definitely not the same. It does say to apply a clear coat, but I am waiting on some bright red powder to come in first. The left one in the last picture is one I bought on ebay for comparison to real chrome. Maybe once the clear coat is on it won't be so orange peel-ey. I think it will be passable atleast. Especially if all 4 match.

Blasted:


Coated, pre-bake:


Coated, post-bake:


Finished (except clear coat):


Also, I checked the chilton's manual and it doesn't list a vacuum diagram.
