Its a L67 not LS67. I have a IC kit I bought used for a my Gen III from a very reputable W body owner and never got around to using it. The exchanger is a radiator from a VW or Volvo I think don't remember which? Works better than the ZZP unit. I'll get pics but want to sell as a whole. If...
Ive got other Buicks for dailys. Just to damn hot in TX in the summer. Maybe after dark a few times but thats about it from June to Sept. Plus to easy to steal and the car draws a lot of attention and can not let it out of my sight.
The guts of the handle are plastic, it will happen over time. If it breaks completely just pull it off and use your thumb. LoL. It's not going to get you stuck anywhere. I upgraded from the stock years ago I got tired of them breaking.
