Yes, as a matter of fact I do own a LUV, several actually, and I do recognize the chopped red luv pictured above; looks alot like the one I saw being sold in Texas for a while.
I do some work with LUVs and just was searching out some 620 info and found this site.
I picked up a 620 rear tinted Bubble window from a 620 the other day and was searching info on these.
My current project LUV is a 72 L.U.V. , 1 year only, especially on alot of the cosmetics and such.
Have a SpeedWay Engineering 9" housing being finished up with Torino flanges, 9-3/8" ring/pinion center section with a 4P Trac-Loc(POSI), 6-lug axles by Strange being tempered & made right now for up to 600HP.
Then shortly we will be installing a Mustang II rack & pinion front suspension with Power Steering.
Trying to keep the old look of the 72 and the L.U.V. but everything underneath is updated and street race ready!
Once I get the custom rear leafs done for it and the front suspension finished, body work & paint then install the 408-700R4 set-up; finish it up then drive it!
Your Varmint truck started out as a slow process as the owner then would do more and more over time to it.
I cant remember when the Chop happened to it but I was able to watch the processes of the louvering, flames, paint etc being done to it.
I know of a few guys down here still around that were heavy into back then and I am attempting to contact them as I can to try to see if the have any pics left from back then....I am hoping!!!
