Re: Formula w/5.7 t top
L98: 2613
LB9: 2592
TOTAL forms: 13,480
total t-tops:6673
You could extrapolate, and figure 6673/13480 = 50% of Formulas recieved T-tops, so divide the L98 number in half to get a rough approximation. That number roughly would track TransAms but GTA's only saw a 28% ratio.
1990 was a very rare year for L98 T-tops

Re: Formula w/5.7 t top
Both cars have just over 100k. T top car has been stored for 23 yrs. Other than a single crack in the dash interior is a 9 out of 10. High option to. Dose have a salvage title.😂 I don't see why! Only damaged bumper fender and door on passenger side. Is there any way to get the salvage changed back to clean?

Re: Formula w/5.7 t top
Are we sure it's an 88 and not an 89 ?

Re: Formula w/5.7 t top
89 and late 91 through 92 are only years you can get "formula 350" with factory ttops in USA.

Re: Formula w/5.7 t top
Unfortunately his book does not break down that figure into Formula 350 vs Formula with t-tops
However, I seem to recall seeing a couple 1988 Formula 350's with t-tops in the past.......but I could be wrong,
they may have been 89's

Re: Formula w/5.7 t top
I've seen 88s but they have C&C tops. Can't say I've ever seen a 350 87-88 90-91.75 with factory ttops

Re: Formula w/5.7 t top
Ok. The Po had parts piled in the car.bumper cover fender lights. You get the picture. Little stuff. I got the stuff out. Most will clean up good. Small 1 inch tare on the top of the back seat. Seats have dent's I hope will come out. I am soaked. Unloaded in the rain. Changing and heading back out to get rpo codes and pic's. When cleaned up still may not be a 9/10. I will let the members of tgo give me their opinions and rate it for me. I will get the rpo codes in a few.

Re: Formula w/5.7 t top
AFAIK this is the only years for T-tops and the 350
87 (maybe 88) GTA & Trans Am in CANADA only
87-89 IROC-Z (not many in 88)
89, 91-92 Formula...
All others 90+GTA/Trans Am/IROC, Should all be suspect
87-88 & 90 Formula should be suspect.
