Score - Ebay parts for my beater & question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

beaterC10 · 02-25-2005, 08:01 PM

Just scored a set of rustfree cali dual tank stepside fenders for my 84. I was the only bidder - can't beat that.

Looks like I might also have a line on a rust free 86 A/C cab in a few weeks.

Guess I can start building my Jonny Cash 73, 77, 79, 84, 86 stepper in a few weeks.

I'm trying to decide if I should title it as a 77, 84, or 86 when I start building it. Does anyone know when cats were first put on 1/2 tons? I understand the legal implications, but I have titles and vins for all of these years and Indiana doesn't seem to look very closely at old vehicles.

in Indiana anything newer than 1973 has to have cats, until you get into 3/4 ton trucks. since they dont check here, you can buy 2 1/4" dual exhaust kits through Summit and Jegs (manufactured by Dynomax, Walker, and Hooker) that dont have provisions for cats. with a mild small block, the 2 1/4" pipes will be more than adequate. of all of the 73-87s i've owned, none of them had cats. i also stripped the cat off of my 93 C1500, and nobody said a word, not even at the exhaust shop when i had my tailpipes put on. i would go with whatever vin is in the cab you're using. IIRC the proper rivets to put it back are like 20.00 a piece.

Not trying to sound like Mr Know it all, but no vehicles had cats 'til '75, did they?

Yeah a cab with air conditioning. The biggest difference are the holes in the firewall, but there are also vacuum operated flapper doors in cowl area that are unique to a/c.
