I own an 88 Iroc convertible with the 305 TPI auto Trans. It includes a 145 speedo, oil cooler, 16inch rims with 245/50/16 rubber, performance rearend, Bose sound system, power everything and many other options.
Seems there is a question about having a 145 speedo in an IROC with the 305 TPI and auto trans...I have seen many others like mine with the 145 speedo, any others out there?
Seems some have the notion that 305 TPI with the auto trans only came with the 110/115 speedo and that the 305 TPI 5 speed trans had the 145 speedo...I know my IROC is not so special that I can have the only 305 TPI auto trans that has the 145 speedo, lets hear from some others that have the 145 speedometer.
