1997 Bluebird GMC B-7 chassis. Tilt column.

I am in need of a complete turn signal switch assy for this bus. My poor local parts supplier doesnt have the needed catalogs to find the correct part and finding Medium Duty GM parts in my area is near impossible.

My searching on Tonkinonlineparts.com didnt turn up any added info either. Found all the items near or associated with the switch but no switch?!

Best guess is to go with Standard Ignition TW20 assy.

Anyone have the correct GM number for the switch? I really want to have correct assy on hand so as not to have it down for a week waiting on parts after getting the old one out for reference.

Many thnks in advance!!!!

I buy an Echlin brand from NAPA part # DL6209. If you add a SB, to the end of the part number, that is the Mileage Plus which is a cheaper brand.

The TW20 and the DL6209 are the same thing (Standard bought Echlin.) If that's the right switch, it's the same one I used in our GM P30 breadboxes with tilt. Back-crossing the numbers comes up with a Delco DL6308D which shows as a GM 1995976. I know you wanted an actual catalog listing, but that's the best I can come up with.

Anyone have the Delco (or even a Bluebird #)number for the alternator for the bus stated above?

It has a 3116 Cat motor. Old alt finally quite after a 1/4 million miles. You gotta love Delco stuff!!

The stamping was almost stamped. I figured out about every other number so I started searching the web. Came up with 19010110 J-mount 3-wire 130 amp alternator. Napa Pro Series 67971.

Thanks!!

That GM number crosses to the TW20/DL6209 as well. The cancel cam crosses to a Dorman (Motormite)83233 or NAPA (Balkamp) 735-2950.

I'd just replace that Delco with a Bosch AL9960LH 160A or a AL9963SB (Bluebird 00120819)200A. Have replaced all my Leece crap with those (except the new 270A and 320A behemoths the SCR equipped buses require.)
