I am talking OEM parts from other car brands, perhaps sourced from a junk yard or bought new.
In my case, here's the list:

1- Fuel pump from a Subaru
2- Relay module and relays from a Toyota
3- Heater valve from a Volkswagen
4- Electric cooling fan from a Kia
5- Fuel cut out switch from a Ford
6- Third brake light from a GMC
7- Exhaust band clamps from a Harley Davidson

Ford( I think) ball valve heater valve, Miata transmission and clutch disc, 7 day mechanical clock from a Russian tank, Volkswagen relays, VDO voltmeter from a boat, facet fuel pump from an Alfa GTV ( not an original Alfa part but that's where it came from)

The only things I can think of are the vintage wood steering wheel, adapted from who knows what, and a GM alternator. But there's also some brackets and stuff that I machined myself.

Hey, Carl,

How much effort were the Miata seats to get fitted?

My '72 is only about 75% MGB. The rest is mostly from Summit, Speedway, Jegs, and Online Metals. Plus the local hardware store. The only parts from another car are the glove box latch from a late-sixties Beetle and the windshield bottom seal from an early-sixties Porsche.

In reply to # 3736677 by JustinSchroder Hey, Carl,

How much effort were the Miata seats to get fitted?

Not difficult at all. Here is how Jim Stuart, Simon Austin, & I did it. There are a few other methods out there, as well.

In reply to # 548394 by V8MGBV8 Miata seat installation thread now available in the MG Enthusiasts BBS archives. Here's most of the good stuff:


Jim Stuart, Maryland, USA,

If you remove the stock seats and fill the captive nuts with studs about 1 1/2- 2" long, it makes everything easier. A trial fit of the Miata seats shows that the front Miata mounting holes almost line up with the studs in the floor. A rat tail file or Dremel will make that a fit. Fender washers will make the bolt up secure.

The rear Miata mounts are extensions rivited to the frame. If you drill out the rivits, they can be re-positioned and reattached either with a nut & bolt or by MIG welding. I have done both with equal success.

Sorry, I never recorded the rear leg positions. Keep the seat frame parallel to the outside sill and work off that point.

Left & right seats have slightly different locations but both can be located the same way. I like using studs, washers and nuts in place of bolts and washers, but either system works.

Hope all this makes sense and helps you with the fitting. E-mail me direct if you need more info.


Simon Austin, British Columbia, Canada,

I may be able to help you out as well, J.B. I did this conversion to my V8 roadster a while back.

Briefly explained, I made up a template of the factory floor holes and made up brackets to fit these. As Jim says, the seats line up pretty well on their own or at least the driver's seat does. For some reason, Mazda moved the passenger seat inside rail out an inch. I made spacer-brackets to over-come this.

If you want to contact me, I can provide more info and pics. FWIW, I used the first generation seats (with the speaker cutouts in the headrests). I don't know if the later seats have the same rail dimensions.


Carl Floyd, Tennessee, USA,


You need to go sit in a Miata. The leg room is not any different (with the seats not the two cars) as far as I can tell. Miata seats are great for those 5'10" & under. The back & back support is not ideal for taller people. I'm 6'2" and I don't find them very comfortable. My dad is 5'5" and loves 'em.

I have them in my '79 B. I found no need to swap the driver & passenger seats. I used the stock mounting holes & bolts. Here's the way I did it:

I cut off the front Miata mounts & welded two 1.5" (approx) Ls for the front "feet" to give some rise for thigh support.

In the back, I straightened the rear Miata mounts to be parallel with the seat tracks. This lowers the seat but causes the seat bottom to hit the floorboard. The Miata seat bottom is thin mild steel so it was bashed in for clearance. The rear mounts are held on by two rivets. I removed the outer rivet & swiveled the mounts inward to work with the stock MG mounting holes. Welded them in place. Once the front was bolted in place & the rear was located, I welded fender washers on the rear mounts since the Miata mount bolt holes are much too large.


Carl Floyd, Tennessee, USA,

"Something else I had to do was swap them side for side as there was a bulge in the seat machanism that wouldn't otherwise clear the frame. Do MGBs have any problem with that?"

No. I didn't have to swap them. The mechanism just cleared on my '79.

I did take the seat bottom apart & scoop out some of the foam cushion with an electric knife to sit lower. I need a lowered floor so I won't have to build such a tall rollbar.
