Chris Meyers lives in Connecticut.
His car is a quarter-elliptic car with a 1275. I honestly didn't know it was for sale.
If you'd like to see his (silver) Midget (in action) it's in this video (he comes onto the screen at about the 2:00 mark)

VRG is sort of "flexible" with classing cars.
They tend to find a class for cars (unless the car is too wild or crazy looking).
For example, my Spridget is really a 1500 rubber bumper Midget. Technically, it's too new for vintage, but it looks like an older Sprite. And my stock engine is slower than a lot of the 1275s. So I basically fit in nicely as a midpack car. They could have turned me away on a technicality, but they didn't. Basically, VRG is laid back about that stuff (but they are strict when it comes to enforcing rules against poor driving).
A Spridget (without flared fenders) could run in the regular Spridget group (usually, that's Group 2 but it depends on the venue). If you start turning much faster lap times, you may be asked to 'move up" a faster group (with MGBs, TR4s, etc)
Ray Stone races with us and he was asked to move up to a faster group after a he started kicking all our butts in the small bore group. Ray was a consistant SCCA National champ when I was back in college (and sort of a hero to me). He's still fast 40 years later. He runs a 948 in his Bugeye (and he told me "it's sort of tired"). He beats most of the MGBs, big TRs etc. He's a stupendous driver.
Note: flared fenders are a no-no in most vintage events, but I've seen some "slight" flares at VRG events and no one says anything. You can't run big, obvious flared fenders like the ones on Hap's car above.
As far as running coil-overs or rear disks, I'm not sure. I haven't seen anyone who is running that setup in our club (I think that's what you mean by LP....yes?). You'd have to ask Mark Palmer, the VRG president (his e-mail is on the VRG website listed below).
There seems to be no real rule about engine prep as long as you keep things reasonable. No modern turbos or 16 valve, trick heads of course. But 1275s in a Bugeye seems to be no real problem (but again, if you start kicking butt, you move up a class.....seems like a fair way to do it in my view).
VRG has an excellent one-weekend race school in the Spring (at New Hampshire). If you do well, they may let you run (from the back of the pack) that weekend. And if you don't have a vintage car, you can use a modern race car to get your license at the school (but you can't race in the vintage races with a modern car) One guy got his vintage license in a SpecMiata last year.
