Hi to everyone! I'm an Italian owner (with terrible English spoken ) of 3 first gen Rx-7. One is a 1980 m.y. coming from USA, one is a 1980 m.y. European and one is a 1981 European restyling.
Some weekes ago I've bought in Ebay the KYB shocks to replace in my 1980 EU. So I will need, in the front, the series H-363003. The seller have shipt to me the H-363010 that will be ok for the restlyling...
Terrible sad, my 1980 EU car is stop for a long time, but now I need to put it on the road (I've change my usually work car and I'm waiting for the new).
When I bought the USA model, the past seller have gived to me a pair of restyling original front suspension kit (shock, struts insert, brakes...): so, to use immediatly the H-363010 that I have here, I can swap with them or I will have problem of toe, camber, caster and/or the front disk are different?
Very very thanks to the person that will help me soon, please if you can use easy English, because I'm an

I take information, and I could check when my mechanics have try to change the shocks, here:

From Mazdatrix.com
We also offer KYB Gas shocks/strut inserts as economical replacements for original equipment. Ride quality is returned to like new. The "GR-2" rear is a lower pressure gas shock. The "Gas-A-Just" is a higher pressure shock and will normally raise the rear of the car approximately 1/2"
All are each, two required per car

79-80 Front H-363003
81-85 Front (12A) H-363010
79-85 Rear "GR-2" H-343140
79-85 Rear "Gas-A-Just" H-KG4644A

To be a (little) more clear, I've this:

I can or there will be some problem?

if you are swapping the whole assembly as pictured in the ebay link, the brake lines have a different thread pitch in 79/80 from the 81/85. Aside from that, I don't think there is any problems, but I'll let someone else answer that.

Thanks for reply I could put the original disc 79/80 on the 81/85's suspension and will be ok? Very thanks!

Much easyer to make two small spacers about 1/8" thick to use the 79-80 inserts into the 1983-1985 housings.

Just a sec: the car is a 79/80, the shocks 4 81/85 model. Them are a little more shorter than the housings in the 2direction.
I can make 2 little cilyndres, down and upstairs to occupy the empty space, it will be ok?

the struts for the 81-85 are shorter than the 79-80 IIRC. so all you need to do is make a spaer to drop into the bottom of the housing to raise the 81-85 strut. members have used stacks of washers before and it worked.

Also my mechanics have told to me this solution, but upstairs the shock (shorten) is not flat but with a little narrowing, and I was scaried that it will, under pressure, brake something in the housing
I don't know if I have explain well, check the photo maybe. Tomorrow I will contact him, for now, very thank to everyone
