Project update on 1977 GMC High Sierra Ole Farm truck

Well here is the dash cluster bezel Iím using for this truck...I had a build thread going but its locked so oh well-here is the restored bezel-I like using a matte clear to protect the woodgrain from fading-not exactly 100% stock but idk-I rather it not fade. Chrome edging restored, thin chrome bead glued on with a thin epoxy bead-and the inner chrome circles are the OE finish-I left them as is-but I restored the chrome edge accent on them.

Re: Project update on 1977 GMC High Sierra Ole Farm truck

Some reference pics of the 78-83 pulse/wiper switch upgrade on this Ď77 GMC. Iíve already added my upgrade sub-harness kit so modding the dash by slightly opening up the existing wiper spot to accomodate the bigger switch. It really doesnt take much-I used a templet matching the 78-83 switch body, opened up the basic cuts using a dremel, then used an assortment of small flat files to smooth out the edges. Then, slide the 78-83 switch in, mark the 2 new mounting spots, drill them and they secure the updated...easy-peasy.

Re: Project update on 1977 GMC High Sierra Ole Farm truck

Following, I've got to get the parts to upgrade mine to a 78' pulse wiper. Nice work.

Re: Project update on 1977 GMC High Sierra Ole Farm truck

The 78-83 style motor is a direct swap out for the 73-77 style BUT-you need to go to the boneyard and grab the little linkage bracket that bolts to the motor shaft-the 73-77 wiper motors have a different size.

Re: Project update on 1977 GMC High Sierra Ole Farm truck

Right now I have my 77' motor hooked up to 81-87 linkage. Will that work?

No-you need to use a 78-83 motor.

Re: Project update on 1977 GMC High Sierra Ole Farm truck

New SPID tag with updated RPO codes for options added as well as the stock stuff. This is NOT a generic LMC tag-I built programs for these and many other items not currently offered by anybody else.
