I was told that the computers would fit where the old one was. You just have to heat the plastic kick panel and reform it. I know you didn't have to worry about smog but I was also told that everything needed to be pretty close to original when the inspector checked out the vehicle ?
The smog ref didn't care where my computer was located, he just had pictures of the smog equipment (provided by AllData), he also wanted to read my OBD1, and that was it. I originally put my ECU in the glove box, cause the DRAC was piggybacked to it. I modified the DRAC for 36" tires. I then had an issue with the referee and using a non-EO VSS. I then got a new VSS, one with an EO number. The DRAC was not compatable anymore, so I removed the DRAC and just left the ECU in the glove. If anyone needs a modified DRAC or needs me to modify or makes theirs adjustable for tire size just let me know.
Yes I believe the ECU will fit behind the kickpanel, without the DRAC piggybacked to it.
DRAC : Accepts a signal from the VSS, and modifies it for the ABS, Electronic Speedo, and ECU. Most Chevies had these if you had ABS, Electronic Speedo, etc.
