On the 65 the plan is to use a pair of used stock front springs that Clint had sent me many moons ago (thanks Clint). I knew I might need them someday. If I remember right, they were from a 69 or 70 small block TH350 2+2 no air. Could be wrong. The question is, will they be suitable for the 65 Sedan? 327/M20 in a 6...

For 67, option # J52 was supposed to be for front disc brakes with 15" tires. I believe this option was only available for Safari wagons. Has anyone ever seen what the original wheel covers looked like for 15" wheels? I haven't found any on the net.

Are there any factory 15x8 steel wheels other than a rally, in the B Body bolt pattern. Did the pattern change in 71? The plan was to use the Wheel Vintiques series 62 on the 65, but if I could find 4 good steel wheels I'd go that route as a cost savings. If available...where would you even find them? Thanks,...

A while back I noticed the inside of both front tires wearing after only 3000 miles on them, and also noticed the upper control arm bushings were looking pretty nasty. I've had a set of NOS bushings sitting around here since long before I got this car and once I saw that I knew where their home would be. Tod...

I noticed today that my "new" front tires (3000 miles) that I put on when I bought my car have a slight bit of wear on the inside and I when I run my hand both directions on them I can feel the difference between the two directions. I know some of my original front bushings are showing their age, so I guess I kno...
