How to ID a front clip

I have a 75 with a later model front clip. Its all a bit of a mish mash, though looks to have 89-91 blazer grill/lights. I'm keen to switch to an earlier grill/lights though want to be sure about compatibility so need to be able to identify my clip/relevant supporting components.

Any tips/advice?

Attached a few pics but happy to get more.

Re: How to ID a front clip

Hello well, it going to depend what style you want 1973-79 (large round headlight) going to need the most parts now. (1980 had option single large square head light). 1981-82 single headlights (1983 1/2 tons had option dual head light, 1984-87 1/2 tons dual head lights standard)- 1984-87 had optional single head light mostly 3/4 up plat forum. The 89-91 blazer grill/lights.
1] wiring, rad support, lights, grill, headlight doors 89-91 only.
2] The 1981-83 single head lights. wiring, rad support, lights, grill, headlight doors 81-83 only.
3]83-87 Dual headlights. wiring, rad support, lights, grill, headlight doors 83-87 only.
4]1980 had option single large square head light. Hood, Fenders, inner fenders, rad support, lights, headlight doors, grill, wiper trans, wiper motor, cowl, cowl screen.
5]1973-1980 single round head light. Hood, Fenders, inner fenders, rad support, lights, headlight doors, grill, wiper trans, wiper motor, cowl, cowl screen.
Off the list.
For the 1973-80 on your 1975 may need mods: Dash pad, wiper switch, cluster face plate, Fuse box. It will depend on what been done what you want use and how much Mods have been done or you have to do to put back or make work.

Off the list. Fuse box 1981-87 may need mods: Dash pad, wiper switch, cluster face plate, Fuse box. It will depend on what been done what you want use and how much Mods have been done or you have to do to put back or make work.

Off the list. Fuse box 1984-87 wiper switch on the steering column may need mods: Dash pad, cluster face plate. It will depend on what been done what you want use and how much Mods have been done or you have to do to put back or make work.

Off the list bumper 1973-80 will be a bolt on 1975 frame, -1981-87 bumper for frame 1981-87 So some Mods may be needed to change or refit older with your clip choice you are going with.

Rad support 81-87 -89-91 hole for the head lights in the location of the frame as you see them fully set up, they look very alike. Sodo make sure you order correct year make sure holes in the rad support for mounting headlights for the year break down. ((Wiring is front lights only, unplug front the firewall back side of the fuse box then dethatch all mounting points to the rad support onto the lights grounds too))

Look up LMC online catalog that help.
I hope this helps get started
