Any runs lately Crider?

No, between being busy and the lousy weather, I haven't been able to get back out to the track

Well I had a little free time, and with the rainy weather today, it was time to get out in the garage and do a little checking on the dragster. I got it up on stands and stripped the wheels and tin off of it so I could pull a string on the centerline and check where the wheelie bars where hitting. Looks like I was about 1/2 off from center. Any thoughts to if that would be enough to drive the car hard in one direction or another? Also found some slop in one of the upper mounting tabs. It seems the whole had wallowed out, I'm thinking that could have been a part of my problem, letting the bars move. So I drilled it out and welded a hardened insert in the hole. I also checked my tire diameter, they are less than 1/8 different, so shouldn't be any problems there. Anything else I should check while I have the car stripped down? Hoping to take it over to elk creek nostalgia event at the and of the month.
