Avanti LSC!

[mfg]

The 1987 Avanti 'LSC'  utilized a .....?....... frame.

1)' Stretched' Monte Carlo.......2) Caprice two-door.......30 El Camino......or......4) Caprice four-door

I'll take a shot. I remember that '87 was the first year for the LSC, and seems like Avanti was still using the Monte Carlo frame in '87...................so I'll say #1 stretched Monte Carlo frame.  (running for cover in case I'm wrong )

The "regular" Avanti coupes were using a Monte Carlo chassis for 1987 when the first LSCs were built.  The LSC was nine inches longer than a coupe.  For 1987 models, I believe that this was done by stretching a Monte Carlo chassis, as Paul said.  For the 1988 model year, I believe that the LSC went to a Caprice chassis.

Paul, Gary......Bad news!....both of your answers are incorrect!

The Monte Carlo had to be shortened for regular Avanti's so I'd guess that the LSC used a stock Monte frame.

Sorry no, a stock Monte Carlo frame wasn't used for this model.

A few 1987s were built on an El Camino chassis, so this may be what you are looking for, even though I do not believe that all of the LSCs were on El Caminos.

That's it! In 1987, the Avanti LSC utilized a Chevy El Camino frame.!
