Floor differences
Is there a difference between a 74 and an 87 2wd automatic floor pan?

Re: Floor differences
I want to say yes. Some trans require a bigger tunnel. I'll wait with you to see what the veterans have to say...

Re: Floor differences
Here are some pictures that show the differences --> http://forum.73-87chevytrucks.com/sm...?topic=11838.0
It looks like there were a number of different styles used over the years. 2wd low hump -- The early ones (73-80) have the hump stopping near the front edge of the seat. See pics #1 & #5 in the above link. While the later ones (81+) have the hump extending back under the seat a little bit. See pic #6 in the above link. 2wd high hump -- The early ones look like they use the same basic floor pan stamping as the low hump except the trans tunnel has been punched/cut out and fitted with a higher bolt-in hump. See pic #3. I'm not sure what year they changed, but the later ones have a high hump that's an integral part of the floor. See pic #7. 4wd high hump -- All 4x4's have a high hump that extends back under the seat for transfer case clearance. The early years have a bolt-in front section and a spot-welded-in rear section. This style is shown in pics #4 and #11 but the seats are blocking the view of the transfer case portion of the hump. A good pic of that can be seen here --> http://67-72chevytrucks.com/vboard/s...59&postcount=7 The later year 4x4's have a high hump that's an integral part of the floor See pic #8 & #10 in the earlier link. |
