Ok you still have the h345, but technically they are the same device that is why a build for one will work on the other with edits to the updater-script to get it to install.  Any way I will give you a list of the repos you need to build with. All of them will be TeaRegular's repos as they are updated more than the ones I had months ago.
You will need the the 
android_device_lge_ms345 repo. If it was a proper recovery for h345 you would use 
android_device_lge_h345, but I am working on making a proper recovery.
You need the 
android_device_lge_c5-common repo.
You need the 
android_kernel_lge_c50.
If you are not building CM you will probably need the 
android_external_mm-dash repo.
Last you need the 
vendor_lge repo. But befor you build you need to go to vendor/lge/c50-common/propriatary/lib/hw and change the name of the camera.vendor.msm8916.so to camera.msm8916.so. Then go vendor/lge/c50-common/c50-common-vendor-blobs.mk and edit line #43 to reflect that name change.
