my L4 chassis is bent and there is a crack on it as well. So i need to get a new chassis. Just wondering if i should just get a replacement L4 chassis or should i go for some conversion kit?

The car will be for outdoor asphalt mod only (i have a CRC Carpet knife for indoor). And i want to keep it a T-bar car. So what would you guys suggest?
Should i just get an AE replacement chassis? or go for a conversion kit? (and which one?)

My L4 was handling like a dream before the damage and I don't want to spend too much money unless there is a real benefit. (like no need to use tape)

Suggestions/comments are welcome!
